Police have flooded Reiger Park, on the East Rand, as two well known gang members are being buried.
The funeral service of Sour Boys member Johnny 'Piet Skiet' Jacobs is underway while the funeral service of Dougans gang member, Gavin Adams, will start at 11am.
There appear to be more policemen than mourners at the Catholic Church.
Marked police cars and Nyalas line the street outside while crime intelligence officers closely monitor the entrance to the church.
Units from across Gauteng have been pulled into Reiger Park, some wearing riot gear, say they are prepared for any potential violence.
Adams’ funeral will follow at the same church.
