The A-level student deported to Mauritius last night has told ITV News she is alone and scared in the country her family fled in 2011.
Speaking on Skype, Yashika Bageerathi described what happened to her yesterday, as she was taken from Yarl's Wood detention centre and placed on a flight accompanied by four security guards, after the last-ditch injunction to keep her in the UK failed.
Now that Yashika Bageerathi has been deported back to Mauritius, her school says it is looking into all the options that might allow her to complete her A-levels.
Ideally, they are hoping that she might be able to return to the UK, but they are also exploring whether it will be possible for her to sit them remotely from Mauritius.
Either way, the students and teachers at Oasis Academy Hadley in Enfield say their fight to help her is not over.
They are also hoping to widen their campaign to raise awareness of the plight of other asylum seekers.
Student Yashika Bageerathi has landed in Mauritius and the 19-year-old has left the airport, ITV News understands.
The Air Mauritius flight deporting A-level student Yashika Bhageerathi has left Heathrow Airport, the airport confirmed.
Before she boarded the plane, Yashika called her mother, asking her what she should do when she arrived at the other side.
Her family, school, lawyers and supporters had campaigned to allow her to stay to finish her A-level exams.
Air Mauritius, the airline due to deport A-level student Yashika Bhageerathi back to Mauritius, where her family and school say she faces "danger" said they "regretted the situation" but had to comply with UK authorities.
Air Mauritius had been contacted by UK authorities during the last weekend, for the repatriation of Miss Bhageerathi.
Considering that all conditions (administrative and security) had not been met, Air Mauritius was not in a position to take the passenger on-board.
Yesterday 1st of April, Air Mauritius received a directive from UK authorities for the repatriation of Miss Bhageerathi.
All conditions having been satisfied, the company had no other choice than to abide by the directive.
The company has taken all steps to ensure that the flight of Miss Bhageerathi takes place in the best possible conditions.
Air Mauritius regrets this situation, but as all airline companies cannot but abide by decisions taken by relevant authorities.
19-year-old Yashika Bageerathi spoke to her mother and her headteacher just as she was getting on to the plane due to deport her to Mauritius.
A last minute injunction to stall the deportation that would have enabled the A-level student to complete her exams failed this evening.
The teenager asked her mother who was going to meet her in Mauritius, and what she should do when she gets off the plane.
Her school and family had urged Air Mauritius to refuse to fly her back to the country where they say she faces danger.
Yashika Bageerathi's school has called on Air Mauritius to refuse to fly her home after an injunction to keep her in the country was rejected.
A spokesman for Oasis Academy Hadley said: "We thought there was a solid legal case for her to stay while she finished her A-levels. It's worrying the legal system doesn't reflect the heart of the people of this country.
"But the plane hasn't taken off yet. This isn't over until it's over. We now ask Air Mauritius not to take Yashika on the plane.
The spokesman pleaded to the airline: "Don't take her from her family to where she faces danger."
The failed last-ditch application to keep Mauritian student Yashika Bageerathi in the country was made as the 19-year-old was being driven to the airport.
She was being taken from Yarl's Wood Immigration Removal Centre in Bedfordshire to Heathrow airport, and is now set to board an Air Mauritius flight at 9pm.
A Home Office spokeswoman said Ms Bageerathi's case "has gone through the proper legal process and our decision has been supported by the courts on five separate occasions".
In such cases, deportation orders are only stayed if a judge decides the case raises issues which are arguable and merit a further hearing.
A judge at London's Law Courts has refused to grant an emergency injunction to block the deportation of Mauritian student Yashika Bageerathi to give her time to take her case to the Court of Appeal.
