A Police underwater team is continuing a search of the River Avon in Bath city centre for missing Bath Spa University student, James Bubear, who was last seen walking along the riverside towards his flat in the Lower Bristol Road on Sunday night.
Police have also released new CCTV images of James they and are appealing for a woman to come forward who spoke to him on the street on the night he was last seen.
James, 19, disappeared after leaving the Vodka Revolution club in George Street on Sunday, March 13, where he'd been at a fancy dress party with friends.
CCTV cameras in the city centre captured him walking alone along James Street West, outside the Odeon cinema.
A short time later, just after 11pm, he is seen talking to a young woman at the junction of James Street West and Charles Street, opposite Green Park Station.
They were together for around five minutes, after which the woman went off and James sat down in a nearby doorway. His mobile phone and passport were found there by a street cleaner the next morning.
Police say they are increasingly concerned for James's safety, as his disappearance is totally out of character and because he has now been missing for so long.
Chief Inspector Simon Ellis said: "It's very important that the woman seen with James contacts us immediately. We believe she may have important information about how James was that night, what his immediate plans were and perhaps which way he was thinking of walking home.
"From the CCTV images it seems that they knew each other and spent about five minutes talking. At one stage they hugged before the young woman went on her way, and James sat down in that doorway for around 15 minutes."
Police say that James is distinctive, tall and slim, and on the night had had his face and eyes coloured by make-up by friends in the club.
Anyone who saw James in the city centre on Sunday night is asked to contact the police on: 0845 456 7000," said Ch Insp Ellis.
