Classes are back in session and students have moved back on campus, but it hasn’t been a happy homecoming for everyone.

There were five reports of offenses involving underage persons reported between Aug. 19 and Wednesday afternoon.

“Offenses involving underage persons” refers to people under 21 years old buying or consuming alcohol.

There were also two assaults reported this week and three reports of disorderly conduct on campus.

In one incident, a male student reported an assault at Lincoln Tower on Friday shortly after 8 p.m. He said he poured water in his roommate’s ear while his roommate was sleeping. The sleeping roommate awoke and became angry before punching and kicking the student several times.

The roommate then locked himself in the room he shares with the first male student, who could hear his roommate throwing things around. The first student called it to the attention of his resident adviser, who called police, and his roommate told police that he had a stressful day.

In another University Police report, a woman not affiliated with the university reported disorderly conduct after she saw a male student grab a trashcan and throw it on the sidewalk during Buck-i-Frenzy. When the woman tried to speak with the student, he was belligerent and visibly upset, according to a police report.

When an officer arrived, he saw the student thrust his body at two female students and blow smoke in their faces.

The officer asked the student to stop and when he tried to pull away, he detained the student. The student calmed down and said he was upset with all the people trying to sell him things at Buck-i-Frenzy. The student was released and the report was sent to Student Conduct.

The first offense involving underage persons occurred Aug. 21 at about 2 a.m. on the Oval.

An officer who was on patrol saw two men and a woman walking west and stopped to watch their progress, according to a police report. But the three stopped walking in the direction they had been going, so the officer went to look for them.

He found them sitting in the grass outside of Derby Hall and they all got up when they saw the officer’s cruiser. The woman ran away from the officer, but the two men stayed to talk with him.

Both men admitted that they had been drinking at a bar on High Street, and one of them admitted to being underage. He gave the officer his fake ID, according to the report.

The officer also advised other University Police members to look for the woman who ran away. They found her east of Derby Hall and the first officer went to speak with her.

After talking with her, he found out that she was 21, but ran away from the police because she had been cited twice before for underage consumption and had bad experiences with officers in the past.

All three were released with warnings.

There were three reports of underage offenses in the early morning hours Sunday, the day after students moved in on campus.

The first was at the 11th Avenue Parking Garage at about 12:30 a.m., and a 19-year-old male student was arrested. He was suspected of using alcohol and had minor visible injuries on his chin and right forearm.

The next incident was about an hour later at the Ohio Union, and two male students — ages 18 and 19 — were arrested. They had nine cans of Natural Light that were taken by the police for evidence.

The third incident on Sunday morning occurred at about 2 a.m. near the Ross Heart Hospital, part of the OSU Wexner Medical Center.

A 19-year-old man was arrested and a credit card and fake ID were seized.

The last incident involving underage persons took place Monday at about 1 a.m. An officer approached an 17-year-old female student who was lying on a bench near Bradley Hall who appeared to be passed out, according to a police report.

When the officer approached the student, she sat up right away and said she thought the bench was a good place for a nap. She didn’t have her keys, BuckID or shoes with her and she said she is “comfortable walking barefoot.”

She had an alcoholic odor on her breath and said she had been drinking, but she didn’t know what she drank or how much, according to the report. The officer said the student and two other individuals she was with were polite and cooperative and arranged for a ride home with ride service Uber.

There were 24 reports of theft between Aug. 19 and Wednesday.
