Police are hunting for a trio of men who used intimidating tactics to rob teenagers of their mobile phones.

The men are said to have approached two 17-year-olds in Morden Park at 12.45pm yesterday suggesting they have knives and demanding the phones.

They are described as a white man, 18 or 19, stocky with black spiky hair dressed in a tracksuit, alongside two men of similar aged who appear to be of Middle Eastern origin.

One is described as thin and in a dark hooded top.
