A British judge is calling for an investigation of mistakes by London police that allowed a man to repeatedly beat and rape a 17-year-old girl from Latvia, according to media reports in the United Kingdom.

Judge Martin Reynolds of Snaresbrook Crown Court on May 23 sentenced Agrol Xhabri, a 22-year-old illegal immigrant from Albania, to 12 years in prison for abducting the girl from her London home, forcing her to work as a prostitute, beating her and raping her at least 30 times, according to The Evening Standard and The Guardian newspapers.

The girl, who had been living with her father, was taken from her home late last year. She escaped once in October and called police, but no help came. In November, she managed to call her mother in Latvia, who called her father in London, who then called police. But when police arrived at a location in East London to rescue girl, they hesitated. While they stalled, Xhabri reportedly beat and raped the girl again.

Xhabri, according to his sentence, is to be deported to Albania after he serves his time in prison.
