A first-year student reported to police that a man grabbed her breasts while she was standing in the serving area of Annenberg Hall around 9:30 a.m. yesterday.

The man, who the student did not know, fled immediately after the attack.

The police are labeling the incident as an indecent assault.

A community advisory sent to first-year students last night said security officers will closely patrol their dining hall, and both uniformed and non-uniformed officers will mingle with students during meal hours.

The student told police her attacker was a six-foot tall dark-skinned white male, who was 18 or 19 years of age and who weighed 180 to 190 lbs. She said the man had brown eyes and thick dark hair. He was unshaven with a lot of stubble.

Police say they have no reason to suspect the assailant was a student.

Students in Annenberg Hall last night said they were concerned that the assault had taken place in an area they generally considered safe.

"You're on your guard when you're outside, but not when you're in buildings," said Anna E. Byrn '04.
