Ten Argentine football hooligans who were said to be planning acts of violence at the World Cup have been deported to Angola after they were detained at South Africa's main airport in Johannesburg.

South African police said Monday in a statement that the men, who are all Argentine citizens, were detained Sunday after arriving at Johannesburg's O.R. Tambo airport on a flight from the Angolan capital Luanda.

"Intelligence indicated that these persons would commit acts of public disorder, engage in acts of violence and provoke conflict with certain fans of opponent teams and other groups from Argentina during the 2010 FIFA World Cup," the statement said.

They were held in custody overnight at the airport before being deported to Luanda at 3:15 p.m. local time Monday, according to Adrian Vernis, attache at the Argentine Embassy in South Africa.
