The Department of Public Safety issued a crime alert yesterday in response to another home invasion incident in a residence hall, the third in the past two weeks.

According to DPS spokeswoman Diane Brown, a man entered an unlocked room in Stockwell Residence Hall, stole the resident"s keys, and then used a key to enter the women"s restroom and look over a shower stall.

The man was described as a black male of medium complexion, with an oval-shaped face. He was reported to be 5-foot-10 inches and 6-foot-2 inches tall and weigh 135 lbs, Brown said. A witness said he was wearing a blue nylon Michigan jacket, black sweatpants, white tennis shoes and a black and red baseball cap.

A number of home invasions and peeping tom incidents have been reported in residence halls this year, including an incident on Feb. 6 when two men assaulted an East Quad Residence Hall resident with a gun.

In response to these incidents, the Housing Department has made a number of changes to increase security in the residence halls, including increasing the number of housing security officers patrolling residence halls, locking the doors 24 hours a day, distributing safety information and holding informational meetings.

The University Board of Regents were briefed about residence hall security measures yesterday at their monthly meeting. The University also announced that it will be conducting a study examining residence hall security that will be released within the next two or three months.

"I"d be interested in an outside opinion as well," said Regent Andrea Newman (R-Ann Arbor). "I don"t think we"re doing enough."

Others have also expressed concern about the security measures in the residence halls. The father of the 18-year-old freshman assaulted in East Quad said the University"s recent security changes should only be the start.

"I think it"s a step in the right direction, but I don"t think it"s enough," he said. "On the Saturday night when my daughter"s incident occurred, the doors were locked."

He added that current security changes would not have necessarily helped prevent similar assaults from happening in the future.

"Without badges or some kind of identification for guests, nobody knew if they were allowed to be there or not," he said.

According to the briefing given to the regents, administrators have responded to "several dozen" parent inquiries.
