BOSTON -- Harvard University police are investigating the third in a series of attacks on students around the Cambridge campus in the last month, the most recent Wednesday morning as a male student was assaulted near Leverett House.

The victim reported that he was attacked about 9 a.m. as he walked Grant Street near Banks Street.

According to the Harvard University police log, the student fought back and was eventually able to flee the scene. He described his attacker as a Hispanic male in his 20s with a medium build, a blue puffy jacket, jeans and black sneakers.

Earlier in May, a female student was attacked leaving Lamont Library by a male who approached her from behind and wrapped a thin wire around her neck. She was also able to escape.

On May 11, the Harvard Crimson reported, another male student suffered a dislocated shoulder after two men jumped out of a car and attacked him as he walked his dog on Plympton Street.

"Obviously, it's being investigated," said Joe Wrinn, a Harvard University spokesman. "We're always concerned about people's safety."

Wrinn said the university is currently in its "reading period" before exams and it's a stressful time for many students who may be distracted and not as vigilant as usual about their own safety.

He said it's important that students take advantage of a university police service that will provide rides if a student is in an unsafe situation. He said the university also provides a shuttle service.

"It's a city environment and people have to be vigilant and careful about what they do," Wrinn said.

Cambridge police said they do not believe there has been a significant uptick in crime around the campus, but will be keeping an eye on the situation.
