This is a brutal moment a butcher is cut down outside his home by an assassin after refusing to pay up to a gangland protection racket.

Victim Isidro Medina de la Cruz, 50, had just got home from his shop in Huimanguillo, in the Mexican state of Tabasco, on 15th May when he was confronted by the gunman on a motorbike.

In CCTV security footage of the slaying Isidro is seen getting out of his car to talk to the biker who pulls out a handgun.

Immediately he fires three shots into the butcher's chest who turns around and tries to stagger into his house for safety.

As Isidro falls to the ground in the porch, the biker runs over and fires seven more rounds into him at point-blank range before fleeing on his motorcycle.

Police and paramedics later declared him dead at the scene.

Isidro had allegedly been threatened over his refusal to pay 'cobro de piso' or 'ground rent' to an extortion gang.

Police are investigating the killing.
