Two elderly women are being sought by police after a wallet was stolen from a bag that was taken off a train.
British Transport Police (BTP) issued a CCTV picture of the pair of grey-haired women clutching the bag on a platform at Sunderland Railway station.
The bag is believed to belong to a student who was travelling on a Metro train and while it was later recovered there was no sign of the wallet. Officers have urged anyone who recognise the women to contact them.
The CCTV images show the women, thought to be in their 70s, with the bag as they walk out of the station in Sunderland city centre. Both were wearing knee-length skirts, white shirts or blouses and carrying shoulder bags. Both are described as having grey hair.
A BTP spokeswoman said: "We are appealing for anyone who may recognise, or have any information regarding the identity of the women to come forward in the strictest confidence.
"We believe the two females may be able to assist with inquiries into the theft of a wallet from a bag at Sunderland Railway Station.
"We have released images of the suspects and are appealing for anyone who may recognise, or have any information regarding the identity of them."
