Manchester Victoria station remains sealed off this morning after a knifeman stabbed three people in a frenzied New Year's Eve attack. 

A critical incident was declared last night and counter terrorism police were drafted in. Forensics teams are currently working inside the station.

A woman and a man - both aged in their 50s - were stabbed by a man at around 9pm as the city prepared to ring in the new year.

The woman had injuries to her face and abdomen and the man has injuries to his abdomen. They were both rushed to hospital, Greater Manchester Police said. 

A police sergeant was also taken to hospital to receive treatment for a stab wound to his shoulder. He has since been discharged.

A man, who witnesses say shouted Allah after the attack, has been arrested and is in police custody. 

The city centre’s inspector said the incident occurred against a backdrop of "a number of serious crime incidents". He tweeted that 15 arrests had been made since 7pm last night.

Assistant chief constable Rob Potts said: "Tonight's events have understandably worried people but I need to stress that the incident is not ongoing, a man is in custody and there is currently no intelligence  to suggest there is any wider threat at this time."

None of the injuries are believed to be life threatening. 

Metrolink are not running any services through the station at present.
