Four arrested over Tetney Lock human leg find
Four people from the Grimsby area have been arrested after a human leg was found in a Lincolnshire canal.
The body part was spotted by a member of the public at Tetney Lock on Thursday and recovered by police.
It is believed the leg was placed in the water and was from a white man in his late teens or early 20s.
Humberside Police urged anyone with information to contact them and warned that people may find "further body parts" in the future.
DCI Mark Oliver said: "It will not be solved without the help of the public who may have seen the disposal of some body parts and may still, unfortunately, find further body parts in the future."
He added that addresses in Grimsby and Scunthorpe were being searched and witnesses were being interviewed.
Police said they hoped information from the public would help identify the victim.
