A reward of up to £20,000 has been offered for information on the murder of a man shot dead while he sat in a car.
Randy Osei-Boateng, 27, was gunned down while he sat in the driver's seat of a parked car in Lakeside Road, West Kensington, west London.
Emergency crews were called to the scene shortly after 4pm on Monday May 9 last year.
Mr Osei-Boateng, who was originally from Ghana but lived in Leigham Avenue, in Streatham, south London, was confirmed dead at the scene.

A post-mortem examination revealed the cause of death was a gunshot wound to the chest.
