The death of a man whose body was found floating in a Swindon stream is no longer being treated as murder.
Police began an inquiry after Robert Wilshire, 47, of Galsworthy Close, was found in the water opposite Dorcan Technology College on 27 September.
Two men were arrested on suspicion of murder but Wiltshire Police said they had now been released without charge.
A spokesman said: "As this is no longer a murder investigation we are not looking for anyone else."
A post-mortem examination concluded that Mr Wilshire died as a result of head injuries.
The police spokesman said: "Concerning the cause of death, this is not for us to say and will be a decision made by the coroner at the inquest."
Following the discovery of Mr Wilshire's body, police appealed for pupils who may have taken photographs or video footage to come forward.
It was thought the pictures may have been published on social-networking sites and may have contained vital evidence.
