On 3 July 2010, a sweep was done at the Bill Stewart Nature Reserve.

The sweep was done to determine the following:
. Any stolen goods hidden away.
. Any criminal activity occurring.
Two senior management members were deployed. During the operation stolen copper cables were found. No criminal activity was present and the situation will be monitored. There were no erected dwellings found and no arrests were made during the operation.
Four people were found in the reserve and searched. No stolen goods were found on them, and they were escorted off the premises
There is still a lot of rubble that was found,indicating that there is a lot of movement within the area.

During the operation several people were spotted coming from Kloof Road up towards the mountain using it as a throughfare.This is an ongoing concern and is also a quick escape route for criminals.
