CHICAGO (CBS) — Aurora Police are now looking for possible additional victims, following the arrest of three men on sexual assault charges.

Charged by Aurora police this week were Corderro A. Pollard, 22, and Eric Stallworth Jr., 21, both of the 1500 block of Kenilworth Place, and Shammrie M. Brown, 25, of the 600 block of South Ohio Street.

Police said the men drank alcohol with the victim at a Naperville restaurant on Aug. 10. The victim and all three men then went to the home Pollard and Stallworth shared on Kenilworth Place. Pollard and Stallworth then had sex with the woman, who was too intoxicated to give consent, police said.

As the investigation progressed, detectives learned that similar incidents that were previously unreported to police may have occurred at the home in the past.

The single-family residence is on Aurora’s West side adjacent to Aurora University. They are encouraging any women who may have been victimized or anyone with information to call investigators at 630-256-5500.

The three men are being held in the Kane County Correctional Center in St. Charles on $300,000 bonds.

Brown did not have sex with the woman, police said, but he was present in the apartment at the time of the assault and made no attempt to stop it.

Pollard and Stallworth are both charged with three counts of felony criminal sexual assault. Brown is charged with one count of felony sexual assault.

Aurora University officials said that the university is cooperating with police in the investigation.

According to charging documents, Stallworth was taken into custody on Tuesday at Aurora University. He was listed as a junior wide receiver on the university’s 2011 football roster, but has not been affiliated with the team during the current season.

Pollard was listed as a junior defensive tackle on the university’s 2011 online football roster. He has no current affiliation with the team, either, university officials said.

According to a 2010 press release issued by the university, Brown was named the school’s Lincoln Academy of Illinois’ Student Laureate Award winner for 2010. The release said Brown was majoring in social work, served as president of the Black Student Association and was a student ambassador for the pre-college experience sponsored by the Quad County Urban League.
