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.

Further tests will be carried out into the death of missing student Souvik Pal. A post-mortem examination carried out was inconclusive.
The father of missing student Souvik Pal will appeal for information about his missing son, one week after his disappearance.
