The company won a contract to sweep the newly-installed Democratic Alliance-run Western Cape government's offices for bugs following a provincial Cabinet decision in 2010.This led to the African National Congress lodging a criminal complaint against Zille. It said that, in hiring Scheepers, she was undermining, and possibly spying on, ANC members.He allegedly obtained cellphone records for his private investigations by applying for authorisation in his capacity as a policeman.Zille previously denied this and went as far as securing a Press Ombudsman ruling against headlines calling him "Zille's spy".
