Seven white men tarred and feathered a white mayor on Saturday as he officiated at a multiracial wheelchair race, police said.

The attackers were arrested for endangering public order, said police spokesman Capt. Reg Crewe. He said it was not known whether they were affiliated with any particular right-wing organization.He said Gus Gouws, mayor of Welkom in the Orange Free State province, was attacked just after he had set off contestants in the wheelchair race. The men poured a sticky fluid and feathers over Gouws, said Crew.

Crew said the men also roughed up Gouws' aide and a traffic policeman who tried to protect the Nationalist Party mayor.
