A prominent neo-Nazi who accused “International Jewry” of seeking world domination has been arrested on charges of domestic violence.

Matthew Heimbach, the 26-year-old leader of the Traditionalist Worker Party (TWP) white supremacist group, was arrested in Indiana on Tuesday.

According to a police report, Mr Heimbach had been having an affair with the wife of his father-in-law Matt Parrot, a TWP co-founder Matt Parrot..

Mr Heimbach had promised the affair was over, but the adulterous couple were reportedly discovered by his own Brooke Heimbach and Mr Parrotin a trailer-home in the early hours of Tuesday morning.

The police report recorded a fight broke out between Mr Parrot and Mr Heimbach. An officer subsequently witnessed Mr Heimbach verbally and physically assaulting his wife at their own home while she was attempting to put their children to bed.

Described by the Southern Poverty Law Center advocacy group  as “the face of a new generation of white nationalists”, Mr Heimbach has regularly disseminated extreme right-wing hate speech about LGBT people, African Americans, and Jews.

An extreme fundamentalist Christian, Mr Heimbach has described Jews as “a truly Satanic enemy”.

“When the Jews are strong, the Jewish people engage their supposed foes with cold-blooded cruelty,” Heimbach wrote in an article titled “Same Enemy, Same Barricades: The Church Against Zionism.”

He was charged on Tuesday with battery and domestic battery committed in the presence of a child under 16 before being released on bond.

Mr Parrot, meanwhile, has announced that he is leaving the TWP, and is shutting down the group’s website.
