Johannesburg - All security measures are in place for the upcoming general elections, police said on Thursday.
"We are confident that our communities can go out in numbers to cast their votes and that they can do so in a safe and peaceful environment," said Lieutenant General Solomon Makgale.
"A stern warning is issued to those who have intentions of attempting to destabilise the election process in any way... they will most certainly face arrest and prosecution."
Over 50 people have already been arrested for election-related offences.
Makgale said police would be deployed to every voting station in the country.
"It must be stressed that normal day-to-day policing and crime prevention duties will continue. Where necessary, reservists will be called up."
On Wednesday, President Jacob Zuma's office announced that he had authorised the deployment of some 2 000 troops to assist the police during the elections and the presidential inauguration.
South Africans overseas finished voting on Thursday. About 27 000 expats had registered to vote.
The next round of special votes will take place on Monday and Tuesday when IEC officials visit 295 731 voters in their homes, retirement centres, hospitals, and healthcare facilities.
The rest of South Africa will head to the polls on Wednesday, 7 May.
