The Chapel Hill Public Library was the target for thieves on Thursday.

Chapel Hill Police Sergeant Bryan Walker says the manner in which the crime was committed is unusual.

“Apparently someone overnight had actually removed glass from one of the doors,” says Walker. “The glass and frame had been removed and was not broken.”

Once the glass was removed someone stole an Apple computer estimated to be worth $2,000 from the library’s teen center.

The crime was discovered by employees when the library opened on Thursday morning. Chapel Hill Police are still investigating the incident.
