Manchester stabbing spree: Police suspect terror motive

A man who stabbed three people at a Manchester shopping centre has been arrested on suspicion of terrorism, British police say.

Police were called to the Arndale Centre at 11:15am on Friday after reports of a stabbing.

The 41-year-old suspect was detained and three people were taken to hospital with stab injuries.

Witnesses described a scene of terror as shoppers, some with injuries, sought refuge in stores.

Police Assistant Chief Const Russ Jackson said the suspect was arrested on suspicion of the commission, preparation and instigation of an act of terrorism.

He added that investigators did not believe anyone else to be involved in the attack, which began when the man lunged at shoppers with a large knife.

He said two unarmed police community support officers intervened and called for assistance, and within five minutes the man was detained by armed officers outside the centre.

"We do not know the motivation for this terrible attack. It appears random, is certainly brutal and of course extremely frightening for anyone who witnessed it," Jackson said.

Police initially said five people were injured, but later changed the figure to four.

A 19-year-old woman and another woman were both taken to hospital with stab injuries, and their condition was described as stable.

A man in his 50s was also hospitalised with stab wounds, while a woman in her 40s was treated by paramedics at the scene but was not stabbed.
