Police Scotland's Major Investments Team has launched a probe into the myster-ious death of 41-year-old Scott McGuire.
It is believed he may have suffered a head injury before he ended up in the water earlier this month.
As reported in later editions of yesterday's Evening Times, police have pledged to investigate any new information.
Mr McGuire, of Hutton Drive, in Govan, was found in the river in Glasgow city centre on July 8. Detectives are looking into a report of a fire nearby on the same morning.
A Police Scotland spokeswoman said: "If anyone has any information to suggest Mr McGuire received injuries before he entered the water, we would urge them to contact officers."
As previously reported by the Evening Times, Mr McGuire's body was pulled from the water near Clyde Street last Tuesday.
Despite a post mortem, his death is being treated as "unexplained".
Detective Inspector Martin Fergus, who is leading the inquiry, said: "We're trying to piece together the last movements of Scott. However, I am looking for the assistance of the local community.
"Our inquiries have revealed that Scott had been sleeping rough near to where his body was later discovered, near to Carlton Place.
"There had been a report of a rubbish fire underneath the suspension bridge at around 5.30am on July 8. I would like to speak to anyone who remembers witnessing smoke."
Anyone with any information is asked to call 101.
