Johannesburg - Democratic Alliance leader and Cape Town mayor Helen Zille was arrested in the Cape Flats for participating in a legal march against drug lords, she told SABC radio on Sunday night.
"The last time I saw anything like this was under apartheid when I was taken in," Zille told the state broadcaster, stressing that several police had ignored arresting drug dealers, but arrested protesters.
She said she had been charged with attending an illegal gathering and would lodge a counter-claim of unlawful arrest.
"The police are being exposed for what they are. There are scores of police and the drug dealers are going ahead with their trade".
This included selling drugs to children.
She said the police were busy with a "purely political" agenda.
Zille said she had been gathering the names of witnesses during the march.
"It's a pity they don't arrest the drug merchants. Everybody knows where they ply their trade."
