Colorado Springs police arrested a man Wednesday suspected in 150 cases of theft of copper valued at $20,000.

Corey R. Miller is suspected of cutting copper backflow valves from dozens of residential sprinkler systems in north side neighborhoods, causing about $60,000 in damage, police said.

Investigators trailed Miller in a neighborhood for two hours Wednesday before they pulled him over and found a dozen backflow valves and burglary tools in his car. He was booked into the El Paso County jail on suspicion of felony theft and felony criminal mischief. Police had been investigating the case since December.

Between January and November 2013 police investigated 513 metal theft cases involving $1.5 million in property loss. That's up from $1.3 million during the same period in 2012.
