In July 2023, Khumalo and members of the
Sizok’thola production team were arrested and charged with murder, robbery, and malicious damage to property following the death of Robert Varrie, an alleged drug dealer, during the filming of an episode in
Katlehong,
Gauteng. Varrie later died after being taken to hospital, prompting the South African Police Service to open a murder investigation. Khumalo handed himself over to police and was released on bail. In April 2025, the National Prosecuting Authority provisionally withdrew the charges to allow for further investigation. On 19 January 2026, Khumalo voluntarily surrendered to police in relation to separate assault allegations linked to a 2025 incident. ActionSA confirmed that he would cooperate with law enforcement. ==Political career==
