Greater Manchester Police have released an image of Souvik Pal, the missing Manchester Metropolitan University student, taken shortly before he left home on New Years' Eve.
Souvik's father, Santanu Pal, says he will stay in Britain until his son is found.
The police officer leading the search for missing student Souvik Pal says there have been no sightings of him beyond 11.05pm that night.
Door staff threw Souvik out of the Warehouse Project for trying to use the ladies toilet, but police say it was a misunderstanding. He took a wrong turn.
A sighting at 1.30am has been shown to be incorrect. Souvik left the club, and was caught on CCTV, just after 11.
