This is the moment alleged phone snatchers are tracked down on the streets of London.
The Metropolitan Police force arrested 230 people and seized more than 1,000 stolen phones after a week of action.
The force targeted those involved in stealing, handling and supplying stolen phones in the “co-ordinated activity”, a spokesman said.
Hotspots include the West End and Westminster, and police had already increased patrols and “plain-clothed operations” in those areas.
It comes as Home Secretary Yvette Cooper has announced she will chair a summit on smartphone theft.
During Thursday’s summit with Ms Cooper, Met Deputy Commissioner Dame Lynne Owens will raise improving security on phones to prevent stolen devices from being easily resold.
