FORT COLLINS - A woman reported being sexually assaulted at knifepoint near College Avenue on the CSU campus in Fort Collins on Thursday night, university officials said.
The woman told police she was walking on the Jack Christiansen Track by College Avenue when a man with a knife attacked her from behind about 10 p.m.
The man was wearing a brown jacket, jeans and work boots, the woman told police.
Police on Thursday night declined to say whether there was a continuing danger to the community, but sent a safety alert to the campus community.
Police cordoned off with tape a grassy and bushy area about 100 feet north of the track, and searched a parked silver SUV.
Colorado State University officials on Thursday night said they did not immediately know if the woman was a student.
The man was last seen heading east toward College, the woman told police.
Christiansen Field is the CSU track and field complex, just west of College between Pitkin Street and University Avenue.
