In one incident, 18-year-old Zacariah Boulares stole a rucksack from a blind couple dining with their young son in Kensington High Street.

Boulares was arrested at his home in February, the same day as his 18th birthday.

As he attempted to evade police by climbing out of the window, Boulares taunted officers and his victims, saying: “I specifically target vulnerable people”.

He pleaded guilty to the offences he was charged with when he appeared in court.

Superintendent Owen Renowden, who leads policing in Kensington and Chelsea for the Met said: “We understand the significant impact that robbery and theft can have on victims – it’s an invasive and sometimes violent crime.

“We’re committed to protecting Londoners and tackling the kind of criminality carried out by Boulares as we make the capital safer.

“His behaviour showed a blatant disregard for others and their belongings, even going as far to admit that he only targets vulnerable people. I commend the determination of officers who brought him to justice.”
