Sari M. Poage ’05, who also lives in Mather, sent an e-mail to the list saying she agreed with Wang.

“If there is a person out there who is assaulting students, a warning delay of a few days can make a very dangerous difference,” she wrote.

Mather House Senior Tutor Bradley S. Zakarin declined comment.

Other students said that Gross’ safety message did little to ease their anxiety.

“I think he covered most areas but I don’t think we’ve seen a lot of these things happening,” said Elizabeth W. Burke ’04. “There was not a timeline of when these things were occurring.”

Another indecent assault occurred last Saturday, when a student was groped in Harvard Yard by a man on a bicycle.

According to Catalano, the incidents seem unrelated because of the different descriptions of the suspects.

On Dec. 2, an undergraduate was cutting through the parking lot of St. Paul’s Church on her way to Dunster House when an unidentified man attempted to rape her, according to HUPD.

Around 7 p.m. on Dec. 11, a graduate student was walking toward Dunster Street when a man coming from the opposite direction allegedly attempted to grab her crotch.

Police said that on Oct. 22, a Harvard student was attacked at approximately 8:30 p.m. when a male grabbed her wrist and waist, spun her around, grabbed her breast and then attempted to remove her coat. The victim struck the face of the suspect, who returned the blow and fled the area.

Three women unaffiliated with the University were groped within blocks of the Quad in separate incidents in October.
