An Accrington man has been found dead at home just hours after being involved in a pub fight.
Gary Leigh, 38, was discovered in his home on Sandy Lane at around 1.40pm on Saturday.
Detectives said he had been out at the National Association of Church and Oswaldtwistle Club, in Straits Lane, Oswaldtwistle on Friday evening, and had been involved in a fight with two men.
He sustained bruises to his body during the brawl but a post-mortem examination has confirmed that his death is not linked to the assault.
A 31-year-old and 37-year-old man from Accrington have been arrested on suspicion of affray and common assault in relation to the incident at the Straits Lane pub and have been bailed until the end of May.
Police are now awaiting toxicology results to establish how Mr Leigh died.
DI Mark Vaughton said: "Although his death remains unexplained, we have ruled out any third party involvement. An investigation is underway into the circumstances of his death and officers are supporting his family."
