In one particular case, during a security raid where a number of illegal miners were arrested, it was discovered that among those arrested were Harmony mine employees that were on leave. The company has increased its number of security guards and has 115 CCTV cameras at working areas. Disused entrances have also been sealed. It has instituted biometric/fingerprint access control and embarked on other security measures to try and prevent the criminals from gaining entrance to the mine. In one other case reported recently a criminal miner was killed and two injured underground when they fell down a steep ore pass when the ladders broke. According to the injured they were a group of nine but the front six managed to get out safely. They were from Matsulu town which is about 70km from the mine. This shows the extent of the influx from outside communities. The injured criminals also reported that there was another group still underground in that same area.
