A British Transport Police (BTP) officer who grabbed a teenage fare dodger by the throat and put her in a headlock has been found guilty of assault by beating.

CCTV footage shows Adrian Young, 48, violently restraining the 15-year-old girl by holding her in a headlock for 30 seconds.

The video from Camden Road Underground station then shows PC Young pushing the young girl back through the ticket barrier and grabbing her throat before shoving her against a ticket machine in September last year.

Afterwards he handcuffed and arrested the girl before de-arresting her at the scene.

A member of the public who witnessed the attack made a complaint and the incident was referred to the IOPC.
