UNC Police are investigating a series of incidents in a residence hall over the university’s winter break.

Authorities say they are investigating a report of a break-in at one room in Spencer Residence Hall and the attempted break-ins at six additional rooms.

Police say they were alerted that suspects tried to gain access to the rooms – one of which was successful – after housekeeping personnel noticed the attempted break-ins after seeing tool pry marks on door jams.

Police say the incidents took place between December 18 and January 3.

Officials say there are no suspects at this time while police are investigating.

Anyone with information is asked to call UNC Police at 919-962-8100 or contact Chapel Hill-Carrboro-UNC Crime Stoppers at 919-942-7515.

Police are encouraging students returning from break to take extra precautions and not allow others to “piggy back” through entrances to residence halls or other campus buildings.
