The South African nationals, who had arrived in Bengaluru and gone incommunicado, have been finally traced by the civic and police authorities in Bengaluru, sources in the health department said on Saturday.

As many as 10 South African nationals were untraceable till Friday evening. Health department officials were worried in the backdrop of detection of the country's first two Omicron cases in Bengaluru, amid testing of all passengers arriving to the state from the 'high risk' countries.
