Karol Czyz, 56, was taken to hospital on 21 March but died three days later

A man has died three days after he was found seriously injured at a property in Lincoln.

Karol Czyz, 56, was discovered in an address on 21 March and was taken to hospital where he remained in a critical condition. However, he died three days later and Lincolnshire Police said his death was being treated as suspicious.

Three men, aged 31, 38 and 43, were arrested on suspicion of attempted murder and have since been released on police bail.

Detectives continue to appeal for information and have re-released CCTV images of Czyz walking down Lincoln High Street on 19 March at 15:36 GMT, when he was last seen publicly, walking with another man near to Tealby Street.

The force believes Czyz visited the South Park convenience shop and continued along the High Street before turning onto Tealby Street.

He may also have travelled through Sidney Street, Bargate and Craven Street.
