Dim lights, loud music and bottles flying.

This matched the description of how some employees described Otto’s Nite Club and Underground, 118 E. Lincoln Highway, early Sunday morning when multiple fights broke out during a private after party to the Young Jeezy Concert.

Donte F. Moore, 21, of Chicago, was arrested during the incident about 1:32 a.m., and another man was expected to be arrested sometime Tuesday for a disorderly conduct charge, said DeKalb Police Sergeant Bob Redel.

Police originally entered the club after seeing fights break out inside and a large amount of people leaving in a hurry. Moore allegedly broke a bottle over the head of a bouncer, and was arrested and charged with aggravated battery.

Otto’s bartender Josh Kawka, who was behind the bar when the fights broke out, noticed the fight start after hearing people screaming. Kawka, along with other bartenders, then jumped over the bar and tried to stop the fight, he said.

The fights continued for about 20 minutes, in which people started throwing and hitting others with bottles, Kawka said. He estimates about 10 to 15 staff members were helping to break up the fights.

At one point, a patron tried to jump over the bar and steal a bottle of liquor before she was stopped by another employee still behind the bar, Kawka said.

Kawka was hit in the face during the fights but did not have any serious injuries. Another employee had a gash under his eye, and the bouncer who Moore hit with a bottle returned to work later that night after being taken to Kishwaukee Community Hospital, Kawka said.

Mike Cabaj, a bouncer working that night who occasionally works for Otto’s, was patrolling upstairs when he heard the fights start. Looking downstairs, he saw a fight between three or four patrons and saw Kawka on the ground getting hit, he said.

When Cabaj went downstairs to try to break up the fight, he saw one person get hit over the head with a bottle and a series of fights break out, he said.

“I’m probably never going to work as a bouncer again because of this,” Cabaj said.

Otto’s General Manager Joseph Karson said he wouldn’t describe the fight as a “huge brawl,” and said there were no more than 10 people fighting at any given moment. Karson was not sure what started the fight, but said the situation was diffused in “a matter of minutes.”

Otto’s has an occupancy capacity of 650, said Karson, who estimates the largest number of people hit about 600 during the night. Karson said about 10 people or so were involved in the fighting, which was about 1 percent of the crowd.

“It’s important to look at the numbers,” he said. “The number of people was not an issue.”

During the Young Jeezy concert, which started at 7:30 p.m. Saturday at the NIU Convocation Center, only one minor incident was reported where two people were escorted out of the concert, said Convocation Center Director John Gordon. He described the crowd as active, but the show went smoothly.

Karson declined to give the name of the “unofficial after-party’s” promoter. Kawka said the promoter who rented the club had been at a previous hip-hop show that was rented out by a different promoter.
