Did you see a man suspected of stealing a bike that had been locked up outside the Post Office on Cleethorpes High Street?
The theft happened between 2.25pm and 2.28pm on Wednesday May 27.
The suspect is said to have arrived on a single decker bus and was seen hanging around a bus shelter for around 15 minutes.
He is then believed to have approached the bicycle, which was chained to another cycle and removed it, before riding off in the direction of Boyes. The lock was also missing.
The suspect wore a dark blue hooded top with a white stripe and light blue hood; dark trousers and white trainers.
The bike had a red frame with a white seat, mudguards and pedals.
Witnesses, or anyone who believes they may have seen the bike for sale, is asked to call Humberside Police on 101, quoting crime reference 2116113.
