Taggers are using Facebook to post possibly incriminating photos of their vandalism around Christchurch.
Truck driver Dig McMahon investigated tags which were left on his vehicle and neighbouring properties, which led him to discover the taggers were posting their handy work on Facebook.
The Star understands that police are aware of taggers posting photos of their graffiti on Facebook, which could be used if they are prosecuted. But police are reluctant to discuss that.
Senior Sergeant Glenn Nalder declined to discuss the matter with The Star.
Mr McMahon said he woke up on Saturday to find his truck and neighbours' property vandalised.
"Some stupid vandals had broken into another neighbours ute, stolen some spray cans and went forth to tag my work truck, which is my pride and joy," he said.
The incident mirrors a similar one in Rolleston last year when a tradesman vehicle was broken into, spray cans taken and used to tag cars and buildings.
Mr McMahon almost caught one of the taggers red handed when he returned during the morning. Mr McMahon believes he was coming back to look at his handy work.
He followed him but the tagger ran off.
Mr McMahon started making inquiries in the area as to who the taggers could be, got a list of names and then began searching on Facebook where he discovered photos of the same tags that had been left on his vehicles
As part of Mr McMahon's investigations he posted photos of the damage on Facebook in a bid to identify the offenders.
He believes that the same taggers may be related to other vandalism in the area and some action needs to take place in order to prevent future incidents.
"More surveillance needs to be placed in the area".
