This is the moment a brazen four-year-old boy marches up to a cash machine and snatches £110 from an unsuspecting member of the public.

CCTV footage recorded at a bank branch in Valpraiso, Chile, on November 20 shows the light-fingered rugrat snatching 97,000 pesos ($150) from under the nose of a man using an ATM.

The man, named as Don Juan Alberto Ibarra in the local press, then wrestled with the tiny thief, who shouted "let me go, let me go".

After Ibarra complained to the bank, he says he was told that the boy was a regular nuisance. However, no action was taken because officials feared a backlash from the boy's parents.

According to local source Estrella Valpo, the child's parents were not at the scene, and the case was being referred to a family court.

In May, police in Brooklyn arrested a 12-year-old on Wednesday (24 May) suspected of being linked to robberies at gunpoint and the assault of an 80-year-old woman.

According to The New York Post, the boy matched the description of a gun-toting thief in several robberies in Coney Island and Bath Beach. He was caught by authorities following three violent encounters with his elderly neighbour.

The boy reportedly confronted the woman and became angry when she did not respond to him. The young suspect allegedly punched the right side of the woman's face, giving her a black eye.

The woman's grandson tried to grab the boy, but called police after failing to catch up to him.
