DENVER -- Police are looking for four men accused of knocking a woman unconscious during the Halloween weekend.

Crime Stoppers released an image Thursday of the men police say are responsible for the assault that occurred at 1550 Market Street shortly after midnight Oct. 30.

Police have not released any details on the events that led up to the assault.

Several of the victims who are law students at the University Denver spoke to Denver7.

They said they were walking down Market St. when they passed another group of men who started making inappropriate comments and then groped two of the women.

"For men to walk around thinking they can just grab women whenever they want and get away with it, that's unacceptable, " said Austin, one of the victims who asked us not to use his last name for privacy reasons.

Austin said he called the men out, which is what lead to the fight.

"I just said excuse you, gentlemen, stop -- and that's how it all ensued," he said. "They were groping; they were physically touching the private parts of these women."

Austin said he got knocked to the ground, cut his forehead and suffered a traumatic brain injury.

"The next thing I remember... there's like three or four of them surrounding me," he further explained.

Maria, who also asked us not to use her last name, said she was also hit by one of the suspects.

"They just got mad for us standing up for ourselves and our bodies, it just got out of control," she said.

Maria was able to snap a blurry photo of one of the suspects and the bloody sidewalk.

"It was just pure adrenaline," she said. "What they did is not right."

The DU law students want to see the suspects caught and said they hope to send a strong message about sexual assault.

"Check yourselves if you think you can walk around society and treat women as pieces of meat," said Austin.
