A popular South African radio and club DJ has been shot dead in the country's largest city, Johannesburg, sending shockwaves across the nation grappling with entrenched crime.

Warrick Stock, popularly known as DJ Warras, was gunned down in the city centre on Tuesday afternoon. Police said the 40-year-old media personality was approached by three suspects, one of whom opened fire on him before fleeing on foot.

The motive of the shooting is unknown and no arrests have been made, police said. It is the latest in a string of killings that have rocked the crime-ridden country in recent years.

Fred Kekana, a local police chief, said Stock was attacked as he was leaving Zambesi House near Carlton Centre. CCTV footage showed a man with dreadlocks opening fire on Stock before fleeing, as the DJ attempted to escape but collapsed shortly after being shot. Stock had an unused firearm on him at the time, and nothing was taken during the attack.

The murder has deepened public concerns over safety, with the South African Police Service appealing for witnesses to come forward. In response to the tragedy, Stock's sister expressed her profound grief, highlighting his role as a voice for many in the community.

Stock's death has provoked a strong public reaction, including statements from government officials and fellow artists, expressing anger and sadness over his senseless murder. Minister of Sports, Arts and Culture Gayton McKenzie remarked on Stock's bravery in addressing difficult social issues through his work.

South Africa's high murder rate, often attributed to gang violence and rampant crime, underscores the escalating challenges facing the nation, which sees over 60 killings daily.
