Pensioner robber hunted

A pensioner is being hunted by police in the US after he pulled off his 13th bank robbery.

The FBI is offering $20,000 for information leading to the arrest of the man - nicknamed the 'Geezer Bandit' - who is believed to be in his 70s and has dodged authorities in California despite being caught on CCTV.

Last week, the mystery man robbed a branch of Bank of America in Santa Barbara, threatening a cashier with a pistol.

It was his first successful raid of the year, and came after 11 similar bank robberies in the San Diego region in 2009, and another in Bakersfield last November.

Investigators are not ruling out the possibility that he could be a younger person disguised as an old man.
