Police arrested a mature student at the Amateur Dramatic Theatre (ADC) bar on Wednesday night after she threatened bar staff and patrons with violence and verbal abuse.

The student, who studies Medieval and Modern Languages (MML)at the University, was refused service at the bar and quickly became aggressive after bar-staff asked her to leave.

According to sources who were present at the scene, the unknown student was shouting socialist slogans, lying on the floor, screaming, standing on tables and attempting to attack patrons of the bar, while her friends tried to persuade her to leave.

A Homerton student who was at the bar that night told Varsity that the girl had tried to punch her and a friend after the pair broke out into a fit of giggles in response to the display in the bar.

"She was shouting at us ‘You’re so fucking lucky, you rich students,’ and then just lunged for us. It was quite funny in a dramatic way," she explained.

When the police arrived she was heard to shout, "Police protect property".

The student was handcuffed and forcibly held to the floor in the foyer of the building for several minutes as a total of four police vehicles assembled outside, including one car containing police dogs, as well as a police van.

As she was restrained in the theatre foyer, the student, from Leeds, was heard threatening police officers with physical violence as well as inviting them to "kick my head in".

Three police officers then carried her out of the building and forced her into the back of a police van as she continued to scream and threaten violence.

Another student at the bar told Varsity that the MML student had expressed regret about not being able to attend the student protests in London that morning and was in the bar to celebrate the opening night of Fired Up.

ADC manager Phil Norris said, "The ADC is run by student volunteers and its management team is made up of recent graduates. This creates a friendly and cordial atmosphere and we are obviously concerned that this atmosphere has been disturbed."

He added, "We see this disturbance as a one-off event, however and don’t expect it to turn into a trend."

The identity of the person arrested has not been confirmed.
