(JTA) — A 21-year-old British man was sentenced to four weeks in jail for sending an anti-Semitic tweet to a Jewish member of Parliament.

Garron Helm pleaded guilty Monday to sending the offending message to Labour Party member Luciana Berger. In addition to the jail sentence, Helm was ordered to pay Berger $128.

The tweet, which called Berger a “communist Jewess,” showed a photograph of her with a Holocaust yellow star photoshopped onto her forehead and the words, “You can always count on a Jew to show their true colours eventually.” It had the hashtag “Hitler was right.”

Helm’s home contained Nazi memorabilia and a flag for an extremist right-wing group called National Action.

“This sentence sends a clear message that hate crime is not tolerated in our country,” Berger said in a statement. “I hope this case serves as an encouragement to others to report hate crime whenever it rears its ugly head.”
