One person was taken to Lawrence Memorial Hospital and four others were arrested after a fight involving more than 30 people broke out early this morning at Gammon's bar, 1601 W. 23rd, according to Lawrence police reports.
Christopher McLeroy, 22, Lawrence, was treated and released after suffering a broken jaw in the scuffle, which started when a group of 25 people demanded entrance into the bar at about 12:15 a.m. today, according to reports.
A doorman of the bar refused to admit the group into the establishment because he said a few members of the group had been involved in a fight there a week earlier, police reports said.
Police reported that members of the group tried to force their way into the establishment, and began fighting with the doormen, security guards and owner.
Three males in their early 20s and a fourth, age 32, all of Topeka, were arrested. Police reports said they were suspected members of a Topeka gang and had returned to the bar to retaliate for a fight that had taken place there last week.
The four who were arrested were the only members of the group who had stayed in the area and were identified when police arrived, according to reports.
At least five employees of the bar were treated at the scene for head and facial injuries. The owner of the bar told police that members of the group were thowing beer bottles and hitting employees of the bar with tables and chairs.
Police reported that a glass display case was broken, the front door was damaged and at least two tables and two chairs were broken, causing $1,000 in property damage.
Police spokesman Chris Mulvenon said at least five patrol cars and six officers were called to the scene.
"This is an ongoing problem at Gammons," Mulvenon said.
