The police watchdog has confirmed they have received complaints from families of Hillsborough victims of police surveillance
Free tickets for a memorial service to commemorate the Hillsborough disaster have been reportedly sold for £100 by touts.
Hillsborough survivors have spoken of how they were "scared and intimidated" by officers from the force investigating the disaster.
Three families of Hillsborough disaster victims have made allegations of surveillance by undercover officers, the police watchdog has said. The Independent Police Complaints Commission said two families allege they were watched and a third says they had property stolen.
Solicitors representing the Hillsborough Justice Campaign are to write to the IPCC to make a formal complaint over claims the police spied on families of the 96.
The Home Secretary Theresa May said the IPCC hadn't received a complaint over allegations families were put under police surveillance after the Hillsborough disaster.
Broudie, Jackson and Canter Solicitors in Liverpool who represented the late Anne Williams said the claims must be fully investigated.
There will be an update on the on going Hillsborough investigation by the Home Secretary later. It follows a damning report from the Hillsborough independent panel into the 1989 disaster.
Theresa May ordered the investigation in December 2012 into the deaths of 96 Liverpool fans and will make a statement to parliament on it's progress.
Former Durham Chief Constable Jon Stoddart is leading the new inquiry.
Preparations are underway for the annual Memorial service for those who died at Hillsborough - 25 years ago. And this year one of the main speakers will be the MP for Leigh, Labour's Andy Burnham.
Five years ago, when he was Culture Media and Sports Secretary, he was drowned out by chanting at the Anfield event. But since then he's played a key role in calling for the new investigation into what happened that day. Daniel Hewitt reports:
The Hillsborough Family Support Group says they remember those who lost their lives at the disaster "every day".
Speaking as details for the 25th anniversary memorial were announced, Margaret Aspinall said:
"Every day we continue to remember those who lost their lives.
"During this 25th anniversary service we will turn on a light for each and every life that was extinguished prematurely and the eternal flame of the Hillsborough Memorial will continue to light our way through the darkest days.
"We expect the service to be busy, so we urge you to obtain your ticket as early as possible and only request the amount of tickets you need. We have also put a closing date of Monday, March 31, so we can plan accordingly.
"For many, April 15 may be a working day and there will be those who are unable to attend. We invite you to join us in thought and spirit and keep us in your prayers at this difficult time."
Details have been announced of a ceremony marking 25 years since the Hillsborough disaster.
The Hillsborough Family Support Group event will be held at Anfield at 2.45pm on Tuesday, April 15th.
Entry is free of charge.
