A police officer was head-butted and seriously hurt while arresting a man at York railway station.
And a second officer was assaulted in the same incident.
Both British Transport Police officers were responding to a call for police assistance by staff on board a Northbound Cross Country service on platform 5 at the station on Thursday night (November 30).
The officers were attempting to escort an abusive man off the train. He was suspected of assaulting a member of train staff.
One of the officers, PC Nick Storey, was head butted in the face, resulting in him losing consciousness on the platform for a short time and leaving him with a serious eye injury.
His colleague managed to handcuff the man who was assisting arrest. In the melee he injured his shoulder.
The man was detained and has since been sectioned under the Mental Health Act.
The injured officer was taken to hospital where he was released after treatment and taken home.
Superintendent Eddie Wylie said: “On a daily basis police officers put themselves in harm’s way to deal with incidents to keep the public safe.
“It’s part of the job, being assaulted isn’t.
“I have spoken to the officer and despite his horrendous injury, he is in good spirits which is a testament to the excellent officer that he is.”
