A hero police sergeant who was stabbed as he helped foil a suspected New Year's Eve terror attack said he had no idea what he was running towards.
Sergeant Lee Valentine was one of three people injured in the knife attack at Manchester Victoria station at about 9pm on Monday.
A 25-year-old man, who was arrested on suspicion of attempted murder, has been detained under the Mental Health Act and a counter-terrorism investigation is under way.
The man is now 'in a secure medical facility', police said today, as they warned it may be months before a decision is made on whether he can be charged.
British Transport Police (BTP) Chief Constable Paul Crowther praised the bravery of Sgt Valentine and his colleagues and said they had averted a tragedy of a far greater scale.

Mr Crowther said Sgt Valentine was 'very lucky'.
'He's got a nasty injury but he could have been much, much worse,' he said. 'He very much feels that it was a team effort and everybody was in this together.
'He got injured in the way he did but I think it's a mark of the man that he constantly wants to emphasise the efforts of all of his team in doing this and I think they did a brilliant job together.'
Sgt Valentine had had been on patrol at the station, nearby the Manchester Arena, along with three colleagues when they confronted the attacker with Tasers and pepper spray.

A couple, aged in their 50s, suffered multiple stab wounds, which are serious but not life-threatening, in the 'random' attack.
