A professor was placed on leave in October and arrested in January after an employee reported seeing possible sexually explicit photos on his computer, CSU said.
Earlier this week, the Colorado State University Police Department received a report of a window peeper on campus.
Just before midnight on January 19, a caller reported a suspect, that was seen masturbating in a tree on the north side of Edwards Hall.
Multiple witnesses described the suspect as a male, and wearing a very dark, possibly green puffy or thick winter coat and black pants. He was also carrying a large backpack.
A CSU security camera captured images of the suspect getting into a vehicle and leaving campus. CSUPD believes the man was driving a white 2008 to 2010 year Toyota Scion XB.
