Manchester Victoria station stabbings treated as terror attack
Two members of the public are still in hospital - as police call it a "horrific attack" on people out to celebrate New Year.
The stabbing of three people at Manchester Victoria station on New Year's Eve is being treated as a terror related incident, police have confirmed.
A 25-year-old man was arrested on suspicion of attempted murder after the attack, which happened shortly before 9pm.
Two knives were recovered at the scene and a property is being searched in the Cheetham Hill area.
In a briefing on Tuesday morning, police said they were keeping an open mind about the motive.
They have not yet confirmed whether the suspect is a British national.
The three victims were taken to a nearby hospital in a "serious" condition but their injuries are not thought to be life-threatening.
A woman in her 50s suffered injuries to her face and stomach, while a man - also in his 50s - has injuries to his stomach.
Prime minister Theresa May tweeted on Tuesday: "My thoughts are with those who were injured in the suspected terrorist attack in Manchester last night. I thank the emergency services for their courageous response."
Sam Clack, a BBC producer who works in the city, was on a platform at Manchester Victoria when he witnessed the attack.
He said: "I just heard this most blood curdling scream and looked down the platform.
"What it looked like was a guy in his 60s with a woman of similar age and another guy all dressed in black.
"It looked like they were having a fight, but she was screaming in this blood curdling way. I saw police in high-viz come towards him. He came towards me.
"I looked down and saw he had a kitchen knife with a black handle with a good, 12-inch blade. It was just fear, pure fear."
Mr Clack said police officers used a Taser and pepper spray before "six or seven" of them jumped on the man.
A New Year's fireworks display in the city's Albert Square went ahead with "increased security".
Ian Hopkins, the chief constable of Great Manchester Police, called the incident a "horrific attack on people simply out to enjoy the New Year's Eve celebrations".
He said British Transport Police officers had showed "incredible bravery" in tackling and detaining the suspect - who remains in custody in Manchester.
"We're currently searching an address in the Cheetham Hill area of Manchester, where it's believed the man has most recently been living," said the chief constable.
