A two-week pause in peeping tom and home invasion incidents ended this week with an armed robbery early Tuesday morning and another peeping tom incident reported in East Quad Residence Hall yesterday.

A student was held up at gunpoint early Tuesday on Church Street, according to reports from the Ann Arbor Police Department.

The victim was walking near the intersection of Church and Willard streets around 2:15 a.m. when confronted by a man carrying a black pistol, according to reports from the AAPD. The assailant forced her behind a building where he stole $400, credit cards, a cell phone and a jacket. The jacket and cell phone were later recovered by police at the scene.

After receiving information from the AAPD, the Department of Public Safety issued two crime alerts yesterday for the incident and the East Quad peeping tom.

DPS spokeswoman Diane Brown said a resident was observed in the shower around 8 a.m.

"She reported that she had locked the bathroom door," Brown said. She added that the victim heard the door open and saw an intruder when she looked down a minute later.

DPS suspects the intruder obtained a key to the women's restroom in a backpack theft from another female earlier yesterday morning.

"It's likely the person went into her room, took the backpack and used the key to get into the shower," Brown said.

Also this semester, DPS issued crime alerts for a home invasion in East Quad Feb. 18, and a home invasion and assault Feb. 3. The crime alert for the Feb. 3 incident was canceled after DPS apprehended two suspects.

"I don't feel really unsafe ... I just think it needs to stop," said East Quad resident and RC freshman Rebecca Frank.

The locks in the women's bathrooms in East Quad have already been changed once this semester, but Brown said officials planned to change the locks again.

"The housing staff will be re-keying all the restrooms this week," she said.

Brown said the locks on female bathrooms have been changed after peeping tom incidents in South Quad, West Quad, Alice Lloyd and Stockwell residence halls.

"I think that it's convenient," Frank said, who added that she didn't mind that all female restrooms shared the same key. "I think that you need to have it public."

Brown says that DPS thinks one or two people are responsible for the peeping tom incidents this semester, and DPS is gathering evidence about several suspects.

In each residence hall, all the women's restrooms share the same key. A peeping tom incident in South Quad in March occurred in coincidence with the theft of keys from an unlocked room in the same hall. "People need to take better care of their keys," Frank said.

Also this week, a room was broken into in West Quad around 10 p.m. Monday, according to DPS reports. An M-card and a pair of Timberland boots were stolen. DPS has no suspects.

DPS has issued crime alerts for two other home invasions in West Quad this semester - one incident on Feb. 6 and another on March 8. In both cases, residents awoke to find a perpetrator in their room. In one case, the suspect fled with a laptop and in the other a laptop had been disconnected. In addition to the incidents in the residence halls, a Compaq laptop was stolen from a room in Mason Hall when a door was damaged to enter the room where it was stored.

Brown said DPS continues to review options to curb incidents in residence halls. But, with the summer approaching, she says that DPS faces less challenges with fewer students on campus and well-staffed summer programs. Brown added she believes the number of incidents will decline. "I just think that it's going to be a combination of factors," Brown said.
