Detective Sergeant James Mullen, of Weymouth CID, said: “Enquiries are ongoing into the incident but at this time we believe that the man died as a result of a tragic accident.
“We would like to thank members of the public who have already come forward to assist our appeal. I am still keen to hear from any witnesses who saw the man enter the water and have not yet spoken to police.”
An investigation is underway following the death of a man who was pulled from the sea off Portland.
