Police in Johannesburg have arrested eleven men, suspected of involvement in recent bouts of violence against immigrants.

Local media reported the army and police joined forces for a raid on an all-male hostel in South Africa’s largest city.

The residence is described as a base for one of the groups believed to have incited xenophobic attacks, attacked buildings and blocked traffic throughout Johannesburg.

Authorities say alcohol, marijuana and electrical equipment – presumed stolen – were found during the raid, as well as a number of weapons.

The government has deployed defence forced in parts of the city deemed hot spots for anti-immigrant violence.
