A former maths teacher who hit a builder with a brick has been jailed.

Geoffrey Butler, 61, challenged the men claiming they were looking through his windows of his home in Margetts Place, Lower Upnor.

A jury at Maidstone Crown Court heard how on February 5, 2018, Butler – who has a previous conviction for waging a hate campaign against his German neighbours – noticed father and son John David Clulow and John Robert Clulow working next door.

The court was told that there were "ongoing issues" between Butler and the two victims due to the building work.

He confronted them and the row escalated when he refused to leave the location. Much of the incident was caught on CCTV.

Prosecutor Bartholomew O'Toole said Butler crossed his arms and told the two men "make me" before spitting.

"The verbal altercation turned physical when Butler brought his head into contact with the head of John junior and a fight started," he said.

"The two then grapple for a period of time and all three fall to the ground. Butler is later seen to kick John Robert Clulow to the groin before picking up a brick and a piece of wood and hitting him in the face."

John junior was left with a cut to the head which required stitches and a black eye while his father had a bloody nose.

Judge Robert Lazarus jailed Butler for nine months telling him that he accepted the first blow came from one of the victims.

"But in my judgment, you should have gone back inside. I have seen nothing that would have warranted you striking anyone with a brick or other weapon. This had nothing to do with self defence.

"I accept you have a serious medical condition and there was a degree of provocation," he said.

Butler had denied the affray and assault but was convicted by a jury.

In 2012 Butler was convicted of racial harassment after playing the Dambusters march and Vera Lynn songs to his German neighbours and performing a Nazi salute.

He waged a four-year hate campaign against Reinhard and Kathryn Wendt, then both 62, after a row over a pocket of land turned sour.

He given a conditional discharge.
