Manchester train station stabbing treated as 'terrorist investigation'

British counter-terrorism police are investigating after three people, including a police officer, were injured in a stabbing at a train station in northern England on Monday.

The attack took place at Manchester's Victoria Train Station shortly before 9pm GMT (10pm CET) on New Year's Eve.

A woman and a man, both in their 50s, were taken to hospital with knife injuries following the attack. They were in a serious but not life-threatening condition, police said.

A British Transport Police officer also receiving treatment for a stab wound was released from hospital on Tuesday.

A man is in police custody and being questioned on suspicion of attempted murder, Greater Manchester Police confirmed.

In a statement on Monday night, Assistant Chief Constable Rob Potts confirmed that counter-terrorism officers were leading the investigation, but said there was "no intelligence to suggest that there is any wider threat at this time".

In a further statement on Tuesday, Chief Constable Ian Hopkins said investigations by counter-terrorism officers with support from Greater Manchester Police would continue "to ensure we get the full facts of what happened and why it took place."

The name of the suspect has not yet been released.

Speaking on Tuesday, Manchester Mayor Andy Burnham condemned the attack.

"Last night's incident at Victoria Station was a vile attack on families seeking to enjoy a peaceful New Year. We're all thinking today of the couple who were injured and of course the police sergeant as well," he said.

British Prime Minister Theresa May said her thoughts were with those who were injured, as she thanked the emergency services for their "courageous response".
