Descriptions of suspected St John's Wood gunmen released

The victims are still recovering in hospital, but are in stable conditions.

At the time of the shooting, the man was in the deli part of the restaurant buying take away food, while the boy was in the main restaurant eating a meal with his family.

One attacker entered the deli and opened fire, pursuing the 31-year-old victim through the main restaurant as he fled.

A second gunman remained outside the restaurant on the street, firing through the restaurant window.

The two men are both described as being of slim build and both wore dark coloured clothing.

The first attacker wore a long-sleeved hooded top, with a covering masking his face up to his eyes.

He is described as being between 5ft7ins and 6ft tall.

The second gunman wore a crash helmet believed to be in a silver-grey colour, with the visor down, as is described as being slightly shorter than the first man.

Both are thought to be in the early 20s.

The duo fled in the direction of Wellington Place, after which they may have got into a dark-coloured car in Cochrane Street.

Acting DCI Sally Jeffrey said: "We really want to hear from anyone who was in the vicinity of Harry Morgan's restaurant at around 9pm on the night in questions, Friday June 26.
