BLOOMINGTON, Ind. (AP) – Police say a weekend confrontation during which an Indiana University student was cut by a meat cleaver was caused by a fight over a woman.

Court documents say 18-year-old Zesen Shen argued with a 20-year-old man during several phone calls after Shen’s girlfriend returned to her apartment building with him four hours later than expected early Sunday.

The Herald-Times reports (http://bit.ly/1iqTngw ) police say Shen got the meat cleaver and had a friend go with him as the other man and four others arrived to confront him at the Tulip Tree apartments. The 20-year-old injured man was treated at a hospital for cuts, the worst being a 4-inch gash on his lower back.

Shen faces felony charges of battery and intimidation. It isn’t clear whether he has an attorney.
