A man arrested on suspicion of murder after a dad was found dead in his flat has been released.
Police said no further action would be taken against the 27-year-old.
Officers discovered the body of Gary Roy Collins, aged 51, at his home on Sackville Street, Barnsley, last Tuesday after concerns were raised by his family.
A post-mortem examination has proved inconclusive and further tests are being carried out to establish the cause of the death.
While formal identification has not yet been carried out, officers are satisfied the body is that of 51-year-old Mr Collins.
