Police are looking for a man suspected of robbing a 12-year-old girl at knifepoint in Camden.
Two males approached the victim on Hampstead Road as she was walking home about 8.30pm on Tuesday, July 11.
One of them threatened her with a knife and told her to hand over her phone.
The suspects demanded the password and then fled the scene once she gave it to them.
The pair were later captured on CCTV walking down the road while using the device.
A 16-year-old boy was arrested on suspicion of robbery last Friday in connection with the incident. He has since been bailed pending further enquiries.
Sergeant Max Pennington, from local policing team in Camden, said: “We have made good progress with our investigation, however we are still keen to identify the other person involved.
“This was a terrifying robbery which took place in broad daylight and we think there will be people who witnessed the incident or recognise the man pictured who can help us to find him and we would urge them to get in touch.”
