Her final text contained just a single word, but it haunts Jean Hanlon's (pictured) family to this day. 'Help', the message read.

A 12-year-old girl was robbed at knifepoint as she was walking home in North London as the police launch an investigation. 

Two males approached the victim as she was walking in Camden, North London, at around 8.30pm on July 11.

One of the suspects threatened the girl with a knife and told her to hand over her phone and give him the password.

Once she had provided him with the passcode, the suspects let her go and she ran away.

Police launched an investigation and gathered CCTV footage from the area, which captured the suspects walking down Hampstead Road looking at the device they had stolen.
