A teenage girl suffered a dislocated shoulder and several officers were injured as police tried to control a huge crowd of students at a train station.

Passengers said trouble flared when police were unable to hold back more than 100 students at barriers at Twickenham station.

There were chaotic scenes as more than 25 police officers, including a dog handler, went to the London Road station at about 5pm on Tuesday.

A boy and a girl, both aged 16, and two 17-year-old boys were arrested for public order offences. A review into policing of the station has been launched.

Edith Williams, 17, a student at Richmond upon Thames College (RUTC), from Battersea, was among those caught up in the incident.

She claimed six officers dragged her out of the station and put her in handcuffs.

She needed treatment after suffering an asthma attack, and her friend was taken to West Middlesex Hospital with a dislocated shoulder.

She said: “I was shocked, my friend went up to them and said: ‘My friend is having an asthma attack’, and they said ‘OK take her to the police station’.

“I couldn’t even breath, I was on the floor.”

Alice Noble, 17, another student, from Streatham, said: “We were all coming home from college and they locked all the barriers so people couldn’t get in.

“They had a big group of teenagers, all rowdy and wanting to get home, they are going to get irritable.

“It was peak time, we all finish at 4.30pm and everybody was walking down to go home.

“As I was leaving the station four or five policemen were carrying one girl – her legs were in the air, for what reason I don’t know.

“The treatment has just been dire, it’s been ridiculous. There’s no reason for the police to act like that.”

Passenger York Membery said: “I can take care of myself, but it was frightening, it was mob rule, the law of the jungle.

“I got through, but my heart was beating, and if a little old lady had been caught up in the melee she could have been crushed to death.”

A police spokeswoman confirmed several officers suffered minor injuries. “British Transport Police are continuing to investigate this matter,” she added.

“A full review of tactics was held on October 7 to identify solutions to assist with the flow of large groups of students arriving at the station en-masse.”

Twickenham MP Vince Cable has written to the principal of RuTC, David Ansell, calling for a meeting to discuss staggering college leaving hours.

He said: “I was at Twickenham station on Monday with hundreds of students, they were good natured, but boisterous and massing on the platform.

“It was intimidating for the passengers and the police were struggling to cope.”

Mr Ansell said: “We will do everything we can to ensure the good behaviour of the students.”

Since the incident a barrier has been placed at the front of the station.

The four arrested teenagers have been bailed to return on November 12.
