A man is in a serious condition in hospital and two other people were injured after they were shot in north-west London.
Police including armed officers were called to Dog Lane in Brent just after 7pm on Monday.
A 17-year-old boy suffered non-life changing injuries, a 21-year-old man has a potentially life-changing injury and the third victim, thought to be in his early 20s, is in a serious but stable condition.
The Metropolitan Police said the suspects fled before officers arrived at the scene.
