London police are looking for public help after a man was injured in a carjacking downtown on Monday evening.

Officers were called to Waterloo and King streets around 6:50 p.m. after a man was assaulted and his vehicle stolen.

Police say when the driver stopped at the intersection a man got in the passenger side, produced a hatchet and ordered the driver to go around the corner.
