A MUSLIM teenager who sparked a wave of controversy after storming off the set of SBS Insight has been arrested after racially abusing a cleaner, it has emerged.

The teen, named by Fairfax as Abu Bakr, allegedly abused the cleaner in an attack last weekend at a Western Sydney shopping centre.

Bakr, 19, who attracted headlines over his fiery performance on the SBS show last week, allegedly threatened and intimidated another man in Bankstown.

The teenager walked off the SBS set after being questioned over his passport being revoked as well as his support for Islamic State fighters.

Abu Bakr, who had his Australian passport cancelled on security grounds, arrived at the SBS studio wearing an Islamic State flag on his jacket.

Police confirmed the teenager was charged with affray and intimidation following the incident last Sunday.

Police said a 43-year-old cleaner at a shopping centre on North Terrace in Bankstown was approached by two men, one of whom allegedly verbally abused and intimidated him.

Bakr and a friend were allegedly kicked out of the centre but returned an hour and a half later and began abusing the man again.

The cleaner contacted security after becoming “fearful” and the men were escorted from the centre.

Police were contacted a short time later and launched an investigation.

The Bankstown teenager was arrested on Friday and police are treating the incident as a hate crime.

Bakr was given strict bail conditions to appear at Bankstown Local Court on Wednesday 10 September 2014.
