There were no suspicious circumstances surrounding the death of 7-year-old Barnsley boy Conley Thompson, police have said following a post-mortem.
Police said they would now focus on how Thompson accessed the construction site where he slipped into a pipe and died.
The results of the post mortem suggest that Conley had, by some means, entered a vertical pipe on a nearby construction site and was unable to get out.
Conley's weight caused him to fall further into the pipe and pushed his clothing up around his body restricting his breathing.
There is no suggestion of any third party involvement.
Our job is to now piece together Conley's movements on Sunday evening and establish how he accessed the construction site.
Forming part of that investigation we will continue to work with the Health and Safety Executive and our thoughts remain with the family and friends of Conley at this extremely difficult time.
