A n*ked man was seen carrying what is believed to be a severed hand after he broke through a window and escaped from a home where he was being held captive by abductors.
The man, who has since been taken to hospital, was shouting: 'Someone help me, I've been kidnapped!'
It is understood the man had his hand badly wounded or severed before or after smashing through the front window of a house in Convamore Road, Grimsby, to escape his abductors.
A picture from the scene showed the man carrying what may have been his own severed hand moments afterwards.
The incident triggered a major response by police and the ambulance service to the scene in East Marsh.
The injured man sought refuge in a shop across the road after the incident late on Saturday afternoon. Paramedics treated him at the scene before he was taken to hospital.
An eyewitness said: 'I was sat at home about 4pm and heard a massive crash.
'I looked out and saw an oldish white bloke had gone crashing through the big window and there was glass all over the front garden.
'The man was completely naked, he had long scruffy hair and blood was gushing from his right arm.
'He was shouting ''someone help me I have been kidnapped''.
'He then ran to the shop and asked for help. Apparently the shopkeeper, who has closed today because of what happened, said he was calm and waited until police came.
'He used the doormat to cover up his bits and pieces.'
It is believed he was being held against his will at the house after being forced to leave another address in Cleethorpes earlier on Saturday.
The image, caught by a shocked passer-by, shows the man naked near the Lifestyle Express corner shop on the corner of Convamore Road and Ropery Street.
His left lower arm is hidden by his body but in his right hand he appears to be carrying something, which is also shown in the shadow cast on the ground.
There are reports he had been beaten in the house, possibly by two men, before he managed to escape by throwing himself through the window.
A terraced house across the road from the shop had its ground floor window almost completely smashed out. It was sealed off by police after the incident.
