A search for a knifeman who stabbed a man in front of terrified passengers on a train continues - as a tube station was evacuated last night amid reports of another knifing.
A man has been left with life-threatening injures after he was stabbed on a train at Beckenham Junction yesterday afternoon.
Police launched an appeal for witnesses to come forward, with no arrests made so far.
Photos show the suspect walking through the streets of London yesterday wearing a mask and armed with a large blade.
Later, Transport for London (TfL) confirmed that Kennington underground station was closed due to a 'customer incident', amid claims on social media of a 'stabbing'. There is no suggestion the Kennington and Beckenham incidents are linked.
Footage from the first incident shows an attacker on top of a man with a large knife in his hand on a train to Beckenham Junction.
One passenger can be heard screaming 'f****** stop it now' before calling police to report the incident.
