This is the horrifying moment a man is brutally attacked and hit in the head with a metal chain.
The pavement outside the Iceland supermarket was splattered with blood after the horrifying attack in Hull on Thursday evening, which was captured by shocking shop CCTV.
Footage, captured by the store's camera, shows the attacker swing what appears to be a metal chain at his victim's head.
The assailant then disappears out of view.
Detectives in at least three police vans cordoned off the bloody scene at about 6pm.
One witness told the Hull Daily Mail: "Something was going on near Iceland, police had it cornered off with about three police cars and van.
"It was all taped off round the shops on that block."
It is believed that the man, who was walking on the opposite side of the road, made his way over to Iceland, ending up outside the entrance of the store.
Staff were seen cleaning up the blood both inside and outside the store by pouring hot soapy water on the ground.
One person posted on Facebook: “Apparently there’s blood all over the path and Iceland is shut up.
"A bit concerned, I only live round the corner....”
A police spokesman said they are aware of the CCTV footage.
Anyone with information about the attack should call Humberside Police on 101.
