A drunk who fatally attacked his own grandfather is filmed glassing a patron in a nearby working men's club - less than an hour after mounting a fatal attack on his own grandfather.

Jakob Walpole, 33, attacked the drinker after he had been confronted for boasting that he had 'lamped' grandfather John Brown, 81, a 'world-renowned' Jaguar restorer who was a regular at the club.

CCTV shown in court charted Walpole's all-day drinking session leading up to the attacks, beginning when he bought a bottle of vodka at a local Spar convenience store.

The footage was relased today after Walpole was convicted of Mr Brown's manslaughter, the glassing of drinker Dennis Hopson and an assault of a barman who as he frogmarched Walpole out of the working men's club following the attack.

Walpole, from Bulkington, Warwickshire, will be sentenced on Monday.
