LEWISTON – Reminders of what happened last week at Bates College are everywhere: drawings of a rape suspect blanket the campus, new alarms guard some buildings and city police cruise by every few minutes.

“You don’t feel safe anymore,” said Aminata Niane, a teaching assistant. “Especially at night.”

The atmosphere around the college has changed since a student was raped early Friday in a campus hall, she said.

The school is now checking student identification for anyone wanting to enter some buildings past 8 p.m. And Bates has hired an off-duty Lewiston officer to patrol during the early morning hours.

Police said Tuesday they had several suspects, including people inside and outside the Bates community. Several people have called police with a possible identification, said Sgt. Michael McGonagle, spokesman for Lewiston police.

Most students doubt it was one of their own, said Matthew Rosler, a first-year student. “Someone would be too likely to be recognized,” Rosler said. “You can’t really hide, it’s so small.”

Amid the fear, the college is trying to go about its business and keep people well informed, said William Hiss, vice president for external and alumni affairs.

In the hours after the alleged attack, the first set of bulletins went up on doors.

Voice-mail messages were sent to every student and staffer at the school.

E-mails were sent too, not only to people at Bates but to an estimated 7,200 alumni.

Niane believes she’s seen fewer people walking around at night. And everybody makes sure that no one is walking outside alone.

Niane said while students and others may be fearful in the wake of the attack, there is not much more the city or school could do to beef up security.

“It’s a pretty safe town,” Niane said. “There are worse places.”
