This man is wanted for a series of thefts along the coast from Newhaven to Brighton.
The man entered buildings in Newhaven, Peacehaven and Brighton in August and September.
The buildings are accessible to the public, but he has gone into more private areas and stolen personal items from bags belonging to people working at the locations.
Subsequently, he has used stolen credit and debit cards to make cash withdrawals and purchases from cash machines and shops in the same area.
Police are now looking to see if he might be linked to other similar incidents.
If you recognise the man or have any information that might lead to his identification, please report online or call 101 quoting serial 879 of 18/08.
