On 27 November 2013, police received information about a suspected stolen SAPS bulletproof vest at Muller's apartment in Port Elizabeth. Warrant officers Van Zyl and Van der Merwe investigated and found the vest on the veranda. Muller's son Jason and Ms Baatjies stated that Jason Uithaler (who "sort of lived" with Muller) had brought the vest to the apartment. When Muller arrived, he confirmed Uithaler's involvement. The vest bore police insignia and a serial number. Van Zyl arrested Muller under section 36 of the General Laws Amendment Act 62 of 1955 for being in possession of suspected stolen property. Muller was detained at Algoa Park Police Station. His daughter later brought Uithaler to the station, but no statement was taken from him until 13 December 2013, when Uithaler stated the vest was his, found in a bin, and that Muller was unaware of its presence. At Muller's first court appearance on 28 November 2013, the screen prosecutor recommended release on warning. However, when the magistrate inquired about previous convictions, Muller disclosed a rape conviction. The magistrate ruled the matter should go to bail court, which was congested. Muller was remanded in custody until 2 December 2013, when he was granted bail of R300. The matter was eventually withdrawn. Muller sued the Minister of Police for damages arising from unlawful arrest and initial detention, and the Minister and NDPP jointly for damages for further detention after the first court appearance. The Magistrate's Court awarded R50,000 for arrest/initial detention and R150,000 for further detention. The High Court dismissed the appeal. The SCA granted special leave to appeal. Muller later abandoned his claim against the NDPP.
