National Police Commissioner General Riah Phiyega said on Tuesday that foreign nationals from 13 countries have been tracked down by police for committing crimes in South Africa.

General Phiyega made this known to the Parliament's portfolio committee on police, during the release of the 2014/15 crime statistics.

She said these countries were Nigeria, Zimbabwe, Mozambique, Somalia, Pakistan, Bangladesh, Ethiopia, Lesotho, Congo, Tanzania, Bulgaria, Malawi and China.

"When you look at the statistics' performances of Limpopo, Gauteng, Mpumalanga and partly Western Cape and KwaZulu-Natal, you understand pressures on policing," she said.
