Martin Montgomery, 31, kicked Nigel Mazs in the head causing him to fall backwards onto concrete after finding him and friends outside his flat in Malakoff Close, Great Yarmouth.

With the help of others, Mr Mazs was able to reach the town centre, where the emergency were called.

He died in hospital 13 days later.

The jury of seven men and five women at Norwich Crown Court today found Montgomery guilty of murder after deliberating for less than 90 minutes.

He had denied the charge but had previously admitted to manslaughter.

His nine-day trial heard that Mr Mazs had been with friends in the stairwell just after 11am on December 22, 2023, when Montgomery came out of his flat, angered at their drug-taking.

Witnesses said he was "shouting and swearing" telling the group there were "f*****g kids here".
