BLOOMINGTON, Ind. (AP) — Indiana University police continued their search Saturday for a man who attacked three students with a sharp-edged weapon as they and two other classmates were walking across campus after leaving a party.

One of the students, an 18-year-old man, received a 4-inch cut to the front of his neck in the early morning attack, said IU Police Capt. Jerry Minger.

The student was taken to Bloomington Hospital, where doctors bandaged his cut, which Minger said was not deep enough to require stitches.

Two women received superficial cuts on their faces in the 12:30 a.m. Saturday attack, which occurred just south of IU's football stadium on a gravel walkway along a campus road.

The five students — two men and three women, all of them 18 or 19 years old — had attended an off-campus party and were about halfway through their mile-long walk back to their dormitories when the attack unfolded, Minger said.

One of the students told officers that a man who had been following the group suddenly began walking at a rapid pace just before the attack. Minger said the suspect pushed his way through the five classmates, slashing three of them and then ran off.

"As he went through group they said that he was waving his arm and was holding a sharp-edged weapon," he said.

Minger said it's unclear if the man was wielding a knife or some other kind of weapon.

So far, police haven't determined the motive for the attack. Minger said the students said they don't know the attacker and don't believe he was at the party they had attended.

The students described the suspect as a slim man wearing a yellow T-shirt, blue jeans and a white hooded sweat shirt.

Minger said several people had contacted campus police with information on who the attacker might be after seeing a composite drawing of the suspect IU police had released.

Detectives met Saturday afternoon to review those tips in hopes that they might lead to a suspect in the case.

"They mapped out how they want to progress from here. They really won't know what's promising and what's not until they start pursuing these," he said.

Minger said police are withholding the students' names until they determine the motive for the attack. He said the injured male student is an American citizen of East Indian ancestry.

Although there's no indication that student's ethnic background had anything to do with the attack, Minger said campus police have increased patrols in areas where international students gather as a precaution.

Campus police sent an e-mail and cell phone text message to students, faculty and staff shortly after 5 a.m. warning them to "exercise caution while walking outdoors."

That message was sent hours after IU tested its emergency notification system on the Bloomington campus. Friday's test was the first full-scale use of the notification system.
