Detectives are making a witnesses appeal after a woman was robbed of a £35,000 watch in Kingsbury.

The 37-year-old woman had advertised the Rolex Pearlmaster timepiece for sale and agreed to meet a potential buyer in Kingsbury Road.

After arriving with her brother two men in a black BMW turned up with one coming out of the car and asking to see the watch.

When the woman handed it to him he ran down an alley into Burmans Road where he got into a black Audi A5.

The driver in BMW then followed the Audi.

The suspects are black and around 25 -35 years old.

DC Tom Palmer from Brent Police said: “This robbery took place at a busy time of day and I am appealing to anyone who saw the altercation or saw someone chasing after another person.”

Anyone who saw the robbery which took place on Friday, 20 September should call Brent Police on 0208 733 3153, 101, or Crimestoppers anonymously on 0800 555 111.
