Police believe Mark Tillotson who has been missing from his home in Barrow since Friday, June 14, could be in Blackpool.
The last time he was seen, he was at Preston railway station and heading towards Blackpool.
The 25-year-old is described as being around 5ft 8ins tall, of medium build with short dark hair.
Officers say he often shaves his hair and grows facial hair, so his appearance could have changed since the last time he was seen, when he was wearing a black and white shirt with dots on, blue jeans, a beige ‘bomber’ jacket, black ankle boots and a black woolly hat.
Mr Tillotson, of Little Croft, Barrow, may also be in the Southport area, police believe.
Anyone who has seen him, or may have information about where he might be is asked to contact Cumbria Police on 101, or crimestoppers anonymously on 0800 555 111.
