The indecent assault is the second of its type in ten days.

On Sept. 16, a University staff member's breasts were grabbed on the "safety path" near Leverett Towers.

Police say they believe that the incidents are unrelated but have not completed their investigation.

They urge students to be alert at all times.

"Students need to be aware of their surroundings," said HUPD spokesperson Peggy A. McNamara.

The police's response to both assaults was delayed because the victims failed to immediately report the crime. Yesterday's incident was reported around 1:30 p.m.--four hours after it happened--while the earlier assault wasn't reported for three days.

McNamara stressed the importance of notifying police quickly when crimes are committed and the criminal might still be in the area.

Nathans wrote in the e-mail message to students that the FDO met yesterday with officials from Harvard Dining Services and the Memorial Hall complex. The e-mail message did not elaborate.
