Eight members of a group called the People's Anti-Drug and Liquor Action Committee (PADLAC) were arrested in September 2007 outside the Mitchell's Plain police station. Zille was then arrested when she visited the police station to investigate. The group had been distributing pamphlets in the campaign against the abuse of alcohol and drugs in Cape Town. Police alleged that she supported vigilante groups opposed to drug abuse. She appeared in the Mitchell's Plain Magistrates Court later that week for contravening the Regulation of Gatherings Act. Zille was expected to sue the Minister of Police for wrongful arrest. Zille subsequently appeared briefly before the Mitchell's Plain Magistrates Court together with a group of ten persons who had been arrested with her.
