Police picked up the 16-year-old girl, from Hackney, and 21-year-old male, from Lambeth as part of an ongoing investigation.
The pair were caught on camera, along with three others, attacking three men to try and steal their iPhones in two separate incidents near Aldgate bus station in central London.
The attack was described by one officer as the most violent he had seen in the last couple of years.
In the first attack, one of the girls can be seen hitting a man over the head in a bid to get his phone as other members of the gang watched.
When he refuses to hand it over they turned on his friend and they ran off with a Ted Baker bag. They were later filmed on a bus stop CCTV camera as they rifled through the bag taking £10 and set of headphones.
They threw paperwork inside the bag away along with a passport following the robbery at 2am on May 14.
The group then stayed at the bus stop, drinking before launching their second attack, again targeting their victim for his mobile phone. Read More
