Police are searching for a pick-pocket who targeted pensioners getting on a bus in Halifax town centre.
Several elderly victims are believed to have been stolen from while they were getting on the bus outside the Goose pub on Commercial Street on Friday October 19.
Similar incidents took place on August 31, with three victims having come forward to the police so far.
Officers believe it is possible there could be other victims who have not yet contacted the police.
Inquiries into the incidents are ongoing and CCTV from a bus that was in the area yesterday has identified a man police would like to speak to about the thefts.
The man in the image, anyone who recognises him, or has any information about the thefts should contact PC Diane Nuttal via 101.
