Police Lt. William Wilson said “he may have wanted to take revenge,” turned and urinated on the leg of a man standing next to him.

The Detroit Free Press reports two other people were sprayed in the process.

The man is to be arraigned June 23.

Police arrested Robert Williams, 52, on the weekend after he allegedly got into a man’s car in Mount Airy Forest and “touched his genitals.”

The man in car was an undercover cop.

Williams has been placed on administrative leave while the case continues.

“We are shocked and dismayed by the news,” said Cincinnati Christian University President David Faust in a statement. “This is a personal tragedy for him and for his family, and we lift them up in our prayers.”

Openly gay students are not accepted by the university, and students who come out can be expelled.

Cincinnati Christian University was founded in 1924 and has about 540 undergraduate students.

Prior to the arrests, an HCU administrator read a letter stating that the university was officially declining their request for dialogue.

On Thursday, Equality Riders met with one student from HCU who described the climate on campus as a “homophobic panic.” He explained that students and staff were discouraged from speaking to members of the Equality Ride.

“The way we were treated today is a clear indication that gay and transgender people are not welcome at this institution. The school’s choice to arrest us shows just how far they will go to suppress the message we bring,” said Jarrett Lucas, Equality Ride co-director. “HCU trains missionaries to go beyond the walls of their school to spread the inclusive gospel of Christ, but today they chose not to uphold the principles they preach.”

The visit to HCU is the sixth Equality Ride stop this year. Now in its third year, the Equality Ride has visited over 50 schools, most of which have been welcoming. At other schools, participants have hosted public forums, participated in panel discussions, and taken part in worship services and Bible studies.

The goal is to inspire further conversation and to empower students, faculty, and administrators to make their school welcoming to all students, a statement from Equality Ride said.

The three women arrested were Caitlin MacIntyre, 19, of Houston, Tex., Katie Higgins, 26, of Charleston, S.C., and Taueret Manu, 21, of the Bronx, NY. The remaining Equality Riders are standing vigil in hopes that students will come out for conversation.
