An alleged bank robber was busted in Germany after a witness identified her by her ‘unforgettable’ backside.

Police say Sandra Meiser raided a bank in the town of Norf south of Düsseldorf. She threatened the bank staff with a gun and got away with some 15,000 euros.

A witness to the attack said the woman had a‘very large’ backside and ‘powerful thighs’, reports Ananova.com website.

Weeks later one witness saw what he believed was the same bottom right in front of him in the queue in the very same branch. He called the police, who arrested the alleged criminal on the spot.

Police found a ski mask and a gun in Meiser’s jacket. She now faces up to 10 years in prison.

The 61-year-old witness was rewarded for his memory with a 5,000 euro cheque.
