Detectives in Oxford have issued a series of CCTV images as they continue to hunt for suspects in several fraud and theft cases.

The footage released on Friday shows a man in a purple shirt going into the Oxford University Press in Jericho, Oxford, on July 26 where police believe he stole a purse. Then he telephoned the victim claiming to be from her bank and got hold of the pin number.

Other images then show a woman wearing a cap using the stolen card at a bank to steal cash. Police are linking the scam with the theft of a purse from County Hall, New Road, on September 10.

The owner was telephoned and asked for their pin number and again the woman is spotted using the card to steal cash. On this occasion the same man was caught on camera waiting outside the bank.

About £1,000 in cash was stolen during the two thefts combined. A man in a light coloured shirt, seen acting suspiciously at the bank, is also wanted in connection with the offences.

DI Simon Morton said: "I would also like to take this opportunity to remind the public to be extremely wary of people who call, or email, claiming to be from their bank. Banks will never ask for your pin number - they will only ask for security questions, such as your birthday or payment details only you would know about."

Police have also released footage of a shoplifter who walked into Wine Rack, in George Street, on July 3 at about 8.40pm. She took two bottles of beer and two bottle of wine and left without paying.

A thief was also spotted on camera grabbing cash from the drivers' tray on a the number five bus to Blackbird Leys in Queen Street at about 12.40pm on August 25. He is seen arguing with the bus driver then reaching across grabbing a fistful of pound coins. Police were unable to say how much was stolen.
