A London-bound train was delayed temporarily while police, armed with what looked like tasers, led a man away away onto the platform.

Police have confirmed the man was being questioned in connection to a stabbing outside The Flying Boat Pub in Spital Street, Dartford.

A passenger, held up during the incident, said while officers conducted their inquiries on board, they gave him a telling off for travelling without a ticket.

The woman, who does not wish to be named, took these snatch pictures of officers on the platform at Sidcup.

She said: "Police armed with tasers came in and went up to a guy, asking him where he had been.

They also said: 'You haven't got a ticket. You shouldn't be on this train.'"

Police spokesman Andy Saunders confirmed the two incidents were connected.

He said it formed part of officers’ inquiries and no arrests were made.
