Shops willing to sell 'stolen' phones

An undercover investigation by BBC London has exposed a black market of shops and traders who are willing to deal in stolen smartphones.

Researchers, who were posing as thieves, offered the phones to traders in Ilford by telling them they had been stolen.

There have been more than 30,000 phone thefts in London in the last year, and police say those prepared to sell stolen phones are "encouraging" the crime.

Mugging victim Alex Causton-Ronaldson and former Flying Squad commander John O'Connor talk about the impact the thefts have.
