Hundreds of demonstrators in London descended on the "Whitehall" government office area Saturday to protest the arrest of right-wing activist and journalist Tommy Robinson.

Part of the area was closed to traffic while the group gathered outside Downing Street on Saturday afternoon, the Independent reported. Protesters were seen carrying signs and waving flags, including ones that said, "Free Tommy." Some protesters got into minor scuffles with police but no arrests or injuries were reported.

What did Robinson do?

Robinson was arrested and jailed Friday after he reportedly streamed live on Facebook as alleged members of an Islamic child sex-grooming gang entered a courtroom building for their trial.

Further details about Robinson’s status were not known as a judge ordered media to not report on the incident, according to published reports.

Britain is dealing with a series of child sex scandals involving gangs led predominately by Islamic men.

What were the charges?

Robinson is the former head of the English Defense League and is a longtime critic of Islam and Islamic migration. He was arrested by police outside the Leeds Crown Court for allegedly breaching the peace and “incitement,” the Independent reported.

According to published reports, many as seven police officers surrounded him and Robinson was heard saying, "This is ridiculous. I haven’t said a word. I’ve done nothing. This isn’t contempt of court. You are allowed to do this, aren’t you?"

Robinson is under a “suspended sentence for committing contempt of court over a gang rape case heard in Canterbury last year,” according to the Independent. Judge Heather Norton sentenced him to three months last year, but suspended it on the condition that he not commit further offenses.

A contempt of court charge can involve speeches or publications deemed to create a "substantial risk that the course of justice in the proceedings in question will be seriously impeded or prejudiced," according to the Independent.
