A Muslim teenager accused of lying to police about being racially abused by three drunk Trump supporters on a Manhattan train appeared in court with a shaved head - a punishment ordered by her Egyptian parents for bringing shame to their family.

Yasmin Seweid was arraigned at Manhattan's Criminal Court on Wednesday for falsely reporting an incident to police and obstructing governmental administration.

The 18-year-old claimed she was singled out by the hate-spewing Trump supporters on December 1 who branded her a 'terrorist' and tried to rip off her hijab when she boarded a subway on her way home from college.

She shared details of the ordeal on Facebook and won the support of other social media users.

Days after reporting the crime, Seweid went missing, sparking a missing person's appeal and another large police effort.

Sources say she made up the elaborate story to cover up for the fact she had been out drinking late with friends.

Her parents ordered her to shave her head as punishment for the scandal. They are also said to disapprove of her Christian boyfriend, The New York Daily News reports.

Among those to support her in court on Wednesday was Seweid's older brother Abdoul who was himself arrested in 2012 for lying to police.

He claimed his friend had been 'assaulted by three unknown males', but was later charged among other teenagers with breaking into cars to steal their valuable contents near their home in New Hyde Park.

Seweid, who is a business major at New York's Baruch College, initially told police she was harassed by three men when she got on the No. 6 train at the 23rd Street station in Manhattan on December 1.

She claimed the drunken white men taunted her, telling her 'you don't belong here' and referred to her hijab as a 'rag.'

Seweid also reported that one of the men grabbed her bag, breaking the strap, and another tried to take off her hijab before she fled the train at Grand Central Station to try and flag down police.

She posted about the 'traumatizing' ordeal on Facebook and it quickly went viral.

'No matter how 'cultured' or 'Americanized' I am, these people don't see me as an American,' she wrote.

'It breaks my heart that so many individuals chose to be bystanders while watching me get harassed verbally and physically by these disgusting pigs.'

Police originally investigated the case as an anti-Muslim bias incident and spent significant resources trying to track down those responsible.

Seweid even provided police with a description of the 'suspects', one of whom cops thought they spotted on video following her when she got off the subway at Grand Central Terminal, according to the New York Daily News.

'She had numerous opportunities to admit nothing happened and she kept sticking by her story', police said.

Authorities looked at surveillance footage but could not find evidence to corroborate Seweid's story.

Investigators had called in the Long Island teen on Wednesday to work on another sketch of her 'attackers' and confronted her with the inconsistencies, the New York Post reported.

'Nothing happened, and there was no victim', an officer told the New York Daily News.

That's when she finally admitted to police that she had fabricated the story, saying she didn't want her parents angry with her for breaking curfew after being out late drinking with friends.

Seweid's strict, Muslim-Egyptian parents allegedly forced her to shave her head over the incident and are upset she is dating a Christian.

She has reportedly been having problems with her family in North New Hyde Park because they feel she's becoming 'westernized', a source told the New York Post.

Seweid was charged with filing a false report and obstructing governmental administration.

She wrote a Facebook post on December 1 detailing an incident in which she was harassed by men who called her a 'terrorist'

Seweid reported that one of the men grabbed her bag, breaking the strap, and another tried to take off her hijab before she fled the train at Grand Central Station to try and flag down police

She was released without bail early Thursday morning following her arraignment in Manhattan Criminal Court.

Neither Seweid or her attorney Benjamin J West would comment, and she didn't speak inside the courtroom. Seweid faces up to a year in jail.

The teenager disappeared for several days after the ordeal and was reported missing by her father Sayeed Seweid.

He was shocked to learn of her arrest, according to DNA Info.

'You try to raise your children as best you can. Maybe she was afraid that night. She was running late,' he said.

'She's a bright, good girl. She's young and maybe she was foolish here. Young kids, you know, you don't understand their mentality.'

Seweid's older sister Sara regularly posts her political beliefs on Facebook. Among photographs shared is one calling for President-elect Trump to be deported.

She could not be reached for comment on Thursday.
