The full text of Greater Manchester Police's latest 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. In a statement, Greater Manchester Police also said: "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.”

British Prime Minister Theresa May joined British Transport Police in commending the emergency services for containing the threat during the incident, which occurred at around 9pm on Monday at Manchester Victoria Station. He added: "We are treating this as a terrorist investigation which is being led by counter terrorism officers with support from Greater Manchester Police. Witnesses to last night's events have praised the British Transport Police officer who was stabbed in the shoulder after 'bravely and immediately' confronting the attacker during a routine patrol. Witness Sam Clack, who came within touching distance of the attacker, said he heard the man shout 'Allah' as he launched the attack. BBC 5 live producer Sam Clack, who had been at the station at the time, said he saw a man stabbed on a tram platform at the station "feet from me". They were "fearless, running towards danger and preventing further harm coming to passengers," he said. A British Transport Police spokesperson said the woman has injuries to her face and abdomen and the man has injuries to his abdomen, while a BTP officer has a stab wound in his shoulder - all of which are described as 'serious but not life-threatening'. The three victims - a woman and a man in their 50s, and a British Transport Police (BTP) sergeant in his 30s - were taken to a nearby hospital in a "serious" condition but their injuries are not thought to be life-threatening.
