Police officers who have reviewed hundreds of hours of night-time CCTV footage have released a timeline of missing Pat Lamb's last-known movements.

The 28-year-old broadcast engineer went missing in the early hours of Saturday, December 13, having begun his night out on Friday December 12 with friends.

Police confirmed today they have identified a number of sightings and have found the very last one is slightly earlier than thought.

Chief Inspector Susie Harper said: "Initial reports to police suggested that the last sighting of Patrick was approximately between half past midnight and 1am.

"However, we have painstakingly reviewed hundreds of hours of both local authority and private CCTV and built up a definitive timeline of Patrick’s movements, which show the last sighting as twenty minutes past midnight on Fairmeadow.

"We have already released CCTV images but are now publishing these timings to provide clarity to all those who have been following the investigation and who have provided us with information."

She added officers meet Mr Lamb's family on a daily basis to keep them informed of progress.
