“The State Police will aggressively seek to arrest and prosecute anyone who is responsible for stealing copper from any State of Michigan facility,” said State Police Lt. Michael Shaw in a statement. “Not only is this extremely dangerous to the persons responsible for these thefts, it is also very costly to Michigan taxpayers and makes driving on the freeway system at night more dangerous.”

Doyle was arraigned Wednesday on malicious destruction of property and other charges. He’s being held on a $25,000 bond at the Detroit Detention Center pending a preliminary hearing set for Sept. 3.

“The arrest of this individual sends a clear signal that this unlawful behavior will not be tolerated,” said MDOT spokesman Rob Morosi.
