Two police officers who allegedly sent racist emails have been suspended on full pay, as Chief Commissioner Ken Lay again warned that the force will not tolerate racism.

A police spokesman said that two constables, one from North West Metro region and the other from Transit and Public Safety Command, had been suspended for "inappropriate email use".

"The Chief Commissioner has made it clear that inappropriate actions including those involving racism will not be tolerated," the spokesman said.

"As these matters are currently under investigation, it would be inappropriate to comment further."

Earlier this month, a stubbie holder which insulted Africans and another with offending comments about indigenous people surfaced and were condemned by Mr Lay.
