Detective Acting Superintendent Craig Morrow would not reveal the timing of the incident but said the footage had led detectives to believe the unidentified man was behind Mr Mohammed's murder.
"I personally believe more so, that it may have been targeted, as opposed to mistaken identity," Detective Acting Superintendent Morrow said.
Authorities are yet to find the weapon used to stab Mr Mohammed, and will not confirm a possible motive behind the suburban killing.
"We're hoping a member of the public may recognise the man, his clothing or his physical movements as he walked along St George St and Beenleigh Road in the early hours of October 25," Det Supt Morrow said.
A $250,000 reward has already been offered for anyone with information that leads to a conviction.
Any accomplice who did not commit the crime may also receive indemnity.
