An elite South African police unit raided the home of the Gupta family, wealthy friends of President Jacob Zuma, on Wednesda.
This was done as part of an investigation into allegations of influence peddling in the government, spokesman Hangwani Mulaudzi said.

A police officer at the compound blocked off access to the street, saying: "This is a crime scene."
