Pregnant woman stabbed and robbed in Bethnal Green

A pregnant woman has been stabbed and robbed on an east London street.

The Metropolitan Police (Met) said the woman, aged in her 30s, was attacked after she approached a taxi in Claredale Street, Bethnal Green at about 05:30 GMT on Tuesday.

The attacker, who had been trying to rob the taxi driver, pushed her into the back of the vehicle and stabbed her in the leg before taking her bag.

The woman, who is 20 weeks pregnant, was taken to hospital for treatment.

The man stabbed her despite her telling him she was pregnant, a Met spokesman said.

The woman's unborn baby was unharmed.

The attacker is described as a "light-skinned" black man in his late teens, 5ft 11in tall, and slim.

He was wearing a cycling mask covering his mouth and nose, but did not appear to have a bicycle.
