According to Greater Manchester Police, the suspect is being held and assessed for mental health issues.
On Monday evening, three people – a couple and a British Transport Police officer – sustained stab wounds in a knife attack at Victoria Station. The suspected assailant was detained minutes after the attack and is currently in custody in Manchester. The officer was discharged from the hospital earlier on Tuesday, while the couple "are still being treated in hospital for their serious injuries," police said.
UK police added that they were "currently searching an address in the Cheetham Hill area of Manchester which is believed to be where the man had most recently been living."
Police also noted that the attack took place very close to the scene of the May 2017 Manchester Arena bombing, which left 23 people dead, including the attacker.
