A 20-year-old woman is dead after being gunned down in the street by attackers on bikes.

Police have launched a murder investigation following the shooting in Malvern Road, Brent, north west London on Friday night.

It is believed she was standing with a group of other people when they were "approached by a number of suspects possibly on pedal cycles", the Metropolitan Police said.

"A firearm was discharged towards the group and the victim was shot," a spokesman said.

"The suspects made off from the scene."

The victim's family have been notified and a post-mortem examination is due to take place on Saturday, police said.
