Rhino horns, hippo teeth and live big cats are just some of the endangered animal items seized by border officials in a record year.
A witness statement given to the high court claims that the information seized contains information which could directly endanger lives.
The independent reviewer of terrorism legislation said he will examine the detention of David Miranda at Heathrow Airport.
The Home Office has denied claims that text messages accusing people of being illegal immigrants are frequently sent to people who have a right to be in the UK.
"We are taking proactive steps to contact individuals who records show have no valid right to be in the UK, some of which date back to December 2008," a Home Office spokesperson said. "We believe it is right to enforce the immigration rules."
The Home Office said private contractor Capita, the firm responsible for the messages, has accepted it sent 14 texts in error out of the 58,800 people suspected of not having a right to be in the UK.
"Out of thousands of people contacted by Capita, a small number have been found to have the right to be in the UK or an outstanding application," the spokesperson added.
Shadow immigration minister David Hanson said Theresa May's immigration system "lurches from one gimmick to another with little effect" following reports people were wrongly sent text messages accusing them of being illegal immigrants.
Mr Hanson said: “The reports that the Government has allowed a private contractor to send British citizens text message telling them to leave the country demonstrates once more just how shambolic and incompetent the Home Office’s border police is under Theresa May.
“Yet again, like the offensive and inappropriate ad vans, the Government will be using taxpayer’s hard earned money to offend and alienate its own citizens.”
An anti-racism campaigner said he was "absolutely shocked and quite horrified" to receive a text message from the Home Office warning him he "may not have leave to remain in the UK."
Suresh Grover, founder of The Monitoring Group, told The Independent, "I thought it wasn't meant for me. I came here with my parents in 1966, I was born in East Africa and have always had a British passport."
Mr Grover, who called the number on the text and spoke to someone at private contractor Capita, said: "The more I talked to the woman the angrier I got. She was asking for more personal information about me and was not telling me where she got my number.
"I think it's outrageous sending people random texts without knowing who they are sending them to ... it's horrific."
More than 100 people have complained to the Home Office after they were wrongly sent text messages accusing them of being illegal immigrants and telling them "to leave the UK", The Independent reported.
A Freedom of Information request submitted by anti-racism campaigner Suresh Grover - who also received the message - shows 39,100 individuals have been contacted in this way.
Of those, 103 have complained to the Home Office and 95 complained to Capita, the private contractor that issued the texts.
Female prisoners at Europe's largest prison for women have been exposed to "intimidation and abuse" by a private security firm which forced them to travel in vans with male inmates.
A surprise inspection at HMP Holloway found joint-venture firm Serco-Wincanton transferring female inmates to the jail in vehicles with men for long periods without a privacy screen.
The male prisoners got out first, leaving the female inmates in the "grubby" vehicle, because reception areas in men's prisons have a fixed cut-off time, HM Inspectorate of Prisons (HMIP) said.
Director of the Prison Reform Trust, Juliet Lyon, warned Serco-Wincanton had risked the safety and wellbeing women who had suffered sexual violence:
"It's time to call a halt to transporting women, many of whom have been victims of sexual abuse and domestic violence, with men in prison vans where too often they are subject to long delays and intimidation."
The Home Office defended its asylum record, after it was blasted for pressuring lesbian and gay applicants to "prove" their sexuality, letting terrorists and war criminals stay and leaving thousands of cases to rumble on.
However, the Home Office defended its records, saying the UK had a "proud history" of awarding asylum to "those who need it".
A spokesman for the department said there were "robust mechanisms" in place to monitor the state of housing provided for asylum seekers.
– Home Office Spokesman
We have robust mechanisms in place to monitor standards of housing provided to asylum seekers.
Following the awarding of Compass contracts, the Home Office and its providers carried out an inspection of accommodation standards and where necessary took action to ensure they met the necessary standards.
Overall the performance of all three providers has shown steady improvement since January and G4S and Serco have made significant investment in their property portfolio. We will continue to monitor performance to ensure that standards are met.
A controversial Government scheme which featured poster vans telling illegal immigrants to return home has "already paid for itself" the Immigration Minister said today.
The Advertising Standards Agency earlier ruled that the controversial posters featured "misleading" arrest statistics and should not appear again in its current form, but did clear the campaign over allegations it was "offensive" and "irresponsible".
Mark Harper defended the £10,000 campaign, arguing it only needed one person to sign up to the scheme to make it cost-effective.
Speaking during a Westminster Hall debate on the campaign, Mr Harper said: "All that we have to do for that pilot to have paid for itself is for a single individual who was in the country illegally to choose to go home as a result of it."
The minister cited the example of a Pakistani national who saw a picture of the van and messaged the number to arrange support for a flight home, as a way the scheme has saved taxpayers money:
"The pilot has actually already paid for itself. If we had to arrest, detain and enforce the removal of one individual, that would have cost the taxpayer probably the best part of £15,000."
John Vine, the Chief Inspector of Borders and Immigration said the Government's "e-borders" scheme had failed to fulfil the overwhelming majority of its intended remit, despite costing the public a billion pounds over ten years.
Outlining the catalogue of failures revealed in his report into the NBTC he said the project needs "fundamentally revised" as its achievement has been "pretty underwhelming."
Immigration minister Mark Harper said UK border technology was the most advanced in Europe, and that the Border Force was making "significant improvements in its performance."
"The 2011 Vine Report revealed that border security checks had been waived without ministerial authorisation consistently since 2007.
"A year ago, the Border Force had trouble with excessive queues at airports. Today, 99% of travellers are cleared within the service standards we've agreed.
"The security of the border is now at the heart of everything Border Force does.
"We have the best coverage of any country in Europe but we are working to improve our coverage further. We will take the findings of the Independent Chief Inspector into account as we continue to develop our API policies and coverage."
Shadow home secretary Yvette Cooper says Theresa May needs to sort out the "catalogue of chaos at border control".
Speaking of John Vine's report findings, she said: "She needs to stop drug-smuggling information being deleted and get the proper border controls in place, rather than relying on divisive gimmicks like ad vans instead.
"The Home Secretary must urgently explain why hundreds of thousands of possible drug-smuggling records were deleted in 2012 without having ever been read.
