Early Tuesday morning, an unidentified person entered several rooms in Lewis Residence Hall and took cash and valuables, said Chris Moody, area director for the quad.
Moody declined to comment on the number of rooms that were burglarized.
But a report filed with University police about one of the incidents stated that $220 in cash was stolen while the room's residents were present and asleep. The room's inhabitants had left the door unlocked, reports state.
University police spokesman Mark McIntyre could not be reached for comment Thursday about the status of the investigation.
Moody, who sent out an e-mail to area residents about the break-ins, said residents must be careful and protect themselves. "We do what we can by keeping the (entrance) doors permanently locked, and we always have an RA on duty," he said.
But Moody said residents should be careful not to let people they don't know into the building behind them. Moody said he suspected that was how the perpetrator entered the residence hall.
As well as watching out for people they don't know, Moody advised residents to keep their doors locked at night and whenever they leave the building.
"This could happen just as easily during the day," he said. "The other thing I've been doing is encouraging residents to file police reports." As of Thursday afternoon, only one report had been filed, but Moody said he had heard of more incidents.
Moody said one problem could be the strong sense of community in the area. "That comes at a price sometimes, by them being too careful and letting their guard down," he said.
