Police described the attack as a "frightening experience" for the victims

A two-year-old girl was punched in the head by two teenage girls during an attempted robbery in north-west London.

The girl was with her mother when the pair were targeted by two female suspects in Preston Road, Wembley, at about 1645 GMT on Tuesday.

They demanded money from the mother, aged 23, before punching her in the arm and attacking her daughter.

The attackers are described as being of Mediterranean appearance and aged between 14 and 18.

"Although the victim and her daughter do not have any visible injuries, this was a frightening experience for them," said Det Insp Rebecca Reeves, of the Metropolitan Police.

"We have released these images in the hope that someone may recognise the suspects and report them to the police."
