British counter-terrorism police are investigating a multiple stabbing in which the suspect reportedly shouted "Allah" at a Manchester railway station on New Year's Eve.
A man and a woman, both in their 50s, and a police officer were being treated for knife injuries following the stabbings last night at Manchester Victoria station.
The 25-year-old suspect in the stabbings at Manchester Victoria Station on New Year's Eve has been detained under the Mental Health Act, police said.
A Greater Manchester Police statement said: "The 25-year-old man arrested last night (31 January 2018) following the incident at Manchester Victoria Station has been assessed by specialist medical staff and detained under the Mental Health Act.
"The Counter Terrorism investigation remains ongoing.
"There is nothing to suggest the involvement of other people in this attack, but confirming this remains a main priority for the investigation.
"The search of the address in Cheetham Hill continues."
GMP Chief Constable Ian Hopkins earlier said: "My thoughts are with the couple who are still being treated in hospital for their serious injuries and with the brave British Transport Police officer who was also stabbed during the attack.
"Police officers at Victoria Train Station responded to a man armed with a knife and swiftly detained him.
"We are treating this as a terrorist investigation which is being led by counter-terrorism officers with support from Greater Manchester Police. They were working throughout the night to piece together the details of what happened and to identify the man who was arrested."
The woman suffered injuries to her face and abdomen and the man was wounded in the abdomen, while a British Transport Police officer sustained a stab wound to the shoulder.
Their injuries were described as serious but not life-threatening.
The incident happened at around 8.50pm when many revellers in the city would have been enjoying New Year's Eve celebrations.
Witness Sam Clack, 38, a BBC radio producer, said he heard the suspect shouting "Allah" before and during the attack.
He quoted the suspect as saying: "As long as you keep bombing other countries, this sort of s**t is going to keep happening."
The city's New Year celebrations went ahead in Albert Square despite the incident, with a firework display taking place as planned, though increased security was brought in.
The city experienced a suicide attack in May 2017, when 22 people were killed and 139 wounded at a concert by the US singer Ariana Grande at the Manchester Arena.
The bomber, Salman Abedi, 22, was born and raised in Manchester.
