Thames Valley Police is appealing for witnesses after a Milton Keynes teenage boy was forced into a car before having his phone stolen.
The incident happened in Milton Keynes on Thursday (27/6) at about 6.50pm.
Four people got out of a blue Vauxhall Astra before chasing two 16-year-old boys from Lanercost Crescent into Lindores Croft.
