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.
