A Welsh man who was jailed for encouraging racial hatred is back in prison after being given a 12 month sentence for harassment.

Trevor Hannington, who was associated with the far-right Aryan Strike Force, was jailed for two years under the Terrorism Act in 2010.

The neo-Nazi had described Jews as “scum” that should be “destroyed”.

At the time, Liverpool Crown Court heard that he used a website to encourage others to: "Kill the Jew, Kill the Jew, Burn down a synagogue today ... Burn the scum."

Mr Hannington admitted owning the Anarchist's Cookbook and The Terrorist Encyclopedia, and admitted publishing instructions on how to make a flame thrower out of a water pistol.

According to a report on the Mail Online, Lindsay Seagrim-Trinder, a potential witness in the original case, had told the police about Mr Hannington’s far-right views.

He called her a “grass” and after his release from prison published her details online as part of a hate campaign.

On Wednesday, Mr Hannington pleaded guilty to putting a person in fear of violence by harassment at Merthyr Crown Court.
