A man’s body was pulled out of the River Calder on Good Friday.
Police were called to the river off Huddersfield Road in Mirfield at about 3pm on March 25 after reports a body had been seen in the water.
Officers recovered the body, which has not yet been identified.
A police spokesman said: “There are not thought to be any suspicious circumstances in the death and enquiries remain ongoing to identify the man.”
The discovery came less than two weeks after a man’s body was found near a canal towpath in Dewsbury on March 14.
The body was discovered by a member of the public near to Low Mill Lane in Ravensthorpe at around 9.15am.
Early indications are that the body is that of a white male, aged between 30 and 50 years who would have been between 5”9” tall and 6”1” tall and of slim build.
He was wearing a No Fear short sleeved t-shirt and chino style shorts with a palm tree design.
Detective Chief Inspector Mark Swift of the Homicide and Major Enquiry team who is leading the investigation said; “Our investigation is at an early stage, and our priority is identifying the victim, with the death presently been treated as unexplained.
“I would appeal to anyone who recognises the clothing, or who has any information, no matter how small or insignificant it may seem to come forward. Enquiries are ongoing.”
Anyone with information is asked to contact police on 101.
