Knockholt: Woman killed in Valentine's Day pub shooting

Det Ch Insp David Higham said call handlers had received reports of a man on the wrong side of the barrier on the bridge.

He said: "We are not ruling out the possibility that he may have entered the water.

"We are currently only looking for one suspect and do not believe there to be an ongoing risk to the public.

"Specialist officers continue to work with the families of both parties involved to support them following this tragic incident."

The suspect, a man who is believed to be known to the victim, left the area following the shooting, police said earlier.

On Saturday morning, Kent Police said it was working to identify and locate "all persons potentially involved".

Local resident Chris Warner told the BBC: "It's a really quiet area. Everybody knows everyone.

"It's just so shocking that something like this could happen here."
