Police in Johannesburg are investigating a man who's been using Twitter to warn motorists about speed traps and other police activity.
PigSpotter, as he calls himself, has now agreed to stop tweeting the location of road blocks but vowed to continue posting speed trap information. He also posts traffic congestion reports, and info about out of action traffic lights and accidents.
Police spokesman Wayne Minnaar told News24 that PigSpotter, or Cliff, was definitely acting illegally. He said: "He will be arrested even if he stops tweeting now. He can be charged with obstructing or defeating justice."
