Police are appealing for information after a pickpocket, who befriended an elderly couple on a train, stole a purse.
British Transport Police says the "audacious theft" happened at Aberdare train station.
On the morning of Wednesday, 9th March an elderly couple boarded a train at Cardiff Queen Street, bound for Aberdare.
During the hour long journey, an unidentified man approached the victim and her partner and attempted to talk with them, seemingly to build their trust, say police.
After they left the service at Aberdare, the couple then made their way down a steep bank towards a waiting pre-booked taxi.
Police have released the above CCTV images of a man they want to speak to.
Anyone with information is asked to call 0800 40 50 40 or send a text to 61016 quoting reference 160 of 21/04/2016.
