A $16,000 reward is on offer for information leading to an arrest

The FBI is hunting an elderly man who is said to have robbed five banks in California in the last three months.

The man - in his seventies - has been dubbed the Geezer Bandit.

In the US a geezer is a word for an eccentric old man: in a previous heist he was reportedly seen wearing tubes connected to an oxygen cylinder.

His latest raid took place in the wealthy La Jolla neighbourhood in San Diego, where he brandished a gun to demand cash before escaping on foot.

Officials are offering three separate rewards totalling $16,000 (£9,559) for information leading to his arrest and conviction.

Authorities describe him as a white man in his seventies, with a thin build, grey hair and an unshaven face.

Surveillance camera footage showed him wearing a baseball cap, blue blazer and several layers of clothing.

Law enforcement officials say he should be considered armed and dangerous.
