Two teenagers have been robbed in Twickenham - one losing his phone and the other his stereo headphones.

The 16-year-old boys were sitting in Moor Mead park near South Western Road when they were approached by two black youths.

The youths tried to start a conversation, then demanded the mobile phones from the other two. They then ran off towards Twickenham.

The suspects are both described as being aged about 17, black and about 6ft 1in tall. One is described as being of stocky build with a chubby face and was wearing a grey tracksuit and black baseball cap.

The other was of slim build and had a moustache. He was wearing a navy hooded top, black tracksuit bottoms and a black baseball cap.

Both spoke in deep London accents using "gang slang".
