READING, Pa. -

Reading police are looking a bicycle-riding copper thief who tears copper out of commercial grade air-conditioning units.

Police describe the thief as white or Hispanic, 18-25 years ago, riding on bicycle.

"The actor is destroying the units as he removes the copper," said a police spokesman.

On June 23, and again on Monday, the thief caused extensive damage at Silk Mill Apartments, 1200 N. 11th St., Reading.

The estimated cost of that damage is $80,000.

He also removed copper from two air-conditioning units at Northeast Middle School 1216 North 13th St. on two days last week, according to police.
