W: Have you heard about the robbery on the jewelry shop in Clifton Road?

M: They planned to arrive as the jewelry was being taken from the safe into the big display window. They arrived in a large red car which they parked on the opposite side d the street.

Once inside the shop, they made the manager of the shop and his assistant lie down on the floor while they filled the briefcases with jewelry.

At that precise moment, a police patrol car arrived. Then the robbery went over.
