University at Buffalo officials have issued an alert following an attempted sexual assault on a woman Friday night at a North Campus apartment complex.

The student said a man followed her into her Creekside Village apartment, grabbed her from behind and choked her. However, she managed to get away and locked herself in a bathroom. The man, police said, left the apartment about 11 p.m.

Police described the attacker as a 6-foot-tall Hispanic male with an average build and in his 40s, wearing a black hoodie and blue jeans, with a pierced ear and black hair.

The student was treated in Millard Fillmore Suburban hospital, Amherst.

The school released an emergency UB Alert message to students’ phones and emails at 12:24 a.m. Saturday. UB also posted safety tips for students and employees on its emergency website.

The investigation is continuing.

Meanwhile, University Police have increased patrols on the North Campus, particularly in the area of the attack.

Creekside Village Apartments, which houses graduate and professional students, is located off Skinnersville Road near the school’s residence halls.
