The skeletal remains of a man have been found by fishermen in the Bristol Channel.
Following the discovery on Tuesday evening, police were called to the riverbank at Chittening Warth, Hallen, near the Esso Oil Refinery, and are now appealing for information.
The human skeleton was discovered partially buried in mud.
The remains have been taken away for forensic examination, but are known to be those of an adult man.
It is not clear how long the man has been dead, how long the remains have been in the channel, or how the man died.
Police say a number of forensic tests will now be carried out to try and establish the cause of death and the age of the remains.
These are expected to take "several weeks".
A team of officers is working on the case at Southmead Police Station, contacting neighbouring forces and Interpol to check missing person records.
