The party is mobilising residents for the establishment of a specialised anti-drugs unit in the area.

Provincial Democratic Alliance leader John Moodey said residents were signing a pettition that would be sent to the Linden police station commander and Randburg Magistrate's Court chief prosecutor .

The marchers want a narcotic bureau to help fight the scourge of drugs.

"Drugs usage in Windsor is very rife and the community has been complaining for a long time, that is why we are calling for this unit," said Moodey.

The DA believed authorities were not doing enough to curb drug-related crimes.

It wanted drug dealers appearing in court to be denied bail.

"The unit must be multifaceted... There should be a prosecutor who focuses on drugs, [the] community must be involved, [and] authorities must have necessary resources."

The march was led by Moodey, ward councillor Laurette van Zyl and local church leaders.

Police spokesman Colonel Lungelo Dlamini said no incidents of violence was reported at the march.
