Nhlamulo Sambo, 18, was killed in Mossel Bay.
More than 400 Mozambicans have been evacuated from Mossel Bay in the past 48 hours after anti-immigration protests turned violent at the weekend, resulting in three deaths and the torching of 55 shacks.
Police confirmed the deaths of two Mozambican men, aged 27 and 43. The third victim, 18-year-old South African Nhlamulo Sambo, was found dead with multiple stab wounds outside a shack. His family fears he was mistakenly targeted as a foreign national because he spoke Xitsonga, one of South Africa's official languages.
Late on Tuesday night, police said detectives arrested a 23-year-old man in connection with Nhlamulo's killing. He will appear in court on Wednesday.
Violence erupted in the Asla Park informal settlement, KwaNonqaba, where a group allegedly set alight about 55 wood-and-iron structures, displacing several families.
