Montgomery County prosecutors say a new wiretapping law helped them track down a notorious drug dealer.
Prosecutors have arrested six people including Ryan Gavlick of Pottstown.
Investigators say Gavlick led a marijuana trafficking ring.
They started tracking him in 2005 but they say he used more than a dozen cell phones to stay ahead of them.
Last December a law that lets police use target-specific wiretaps for situations like this finally took effect.
Last month prosecutors say they used that technology to arrest Gavlick and his supplier during an alleged drug deal.
