A man was seen “clutching his chest” after a stabbing that led to a Tube station being closed.

Seven Sisters station on Seven Sisters Road was closed this morning (July 23) after reports of a serious assault at 8.48am.

A male, whose age has not been mentioned, was taken to hospital with injuries consistent with "being stabbed", the British Transport Police said.

His injuries are thought to be life threatening.

One person, who wishes to be anonymous, said she was on her way to work when she saw a man “clutching his chest saying he’d been stabbed”.
