We can only wait and see...
@Slowhands, I live about 4-5 houses from you in Burgundy street.. Telkom's contractor replaced the manhole cover on my lawn in front of the house with a new square one with THICK concrete around it (This was about 12 days ago..)
That same evening the thieves were out and about in the street in fact opposite your neigbour (policeman) and opened their round manhole and hack sawed the thick cable. Within two minutes, two of SJC security's cars were driving around looking for the guys.
Too late, the thieves ran into the field towards Corrobrick. I picked up the thick roll of Telkom cable and informed the police that arrived that I'll keep it in my garage, rather than the thieves coming back for the loot.
Only 2-3 of these manhole covers (with the built-in locks) were replaced.. The rest that can be lifted open by anyone are still around.
