( CNN ) An attempt to mend the relationship between citizens and police in St. Louis broke into a shouting and shoving match late Wednesday -- between citizens and police . Council members considering a bill to establish a civilian oversight board over police work were holding a public meeting when Jeff Roorda , the business manager of the city 's police union , and a woman appeared to get into a confrontation , an online video shows . The room erupted into shouts and profanity , as people rose to their feet and crowded in on the two . The bill was sponsored by Alderman Antonio French , an active participant in demonstrations that erupted in August in the streets of Ferguson , Missouri , after police Officer Darren Wilson , who is white , shot and killed unarmed African-American teen Michael Brown . A grand jury declined to file charges against Wilson , who resigned from the force . St. Louis police were investigating Wednesday night 's scuffle . `` A police report with multiple complainants has been filed relative to the incident , '' said spokeswoman Schron Y. Jackson . `` There is an ongoing investigation to determine what occurred , '' she said . There were no arrests or injuries , she said Thursday . The meeting was packed . It was meant to seek public input into the creation of a civilian oversight body that can independently investigate police misconduct . For about an hour , the hearing went on without incident , as residents and police officers got up to speak in favor of or against the need for such a board . `` The alderman listened to their opinion and listened to our opinion . I thought the meeting was going really well , '' said Bishop Derrick Robinson , a Ferguson preacher and protest organizer who was at the meeting . Roorda disagrees . He said protesters shouted police down . `` About 30 or 40 anti-police radicals ( were ) fomenting violence against the police , '' he said . Roorda is a Missouri state representative and the business manager of the St. Louis Police Officers Association . He showed up at the meeting wearing a blue wristband reading `` I am Darren Wilson . '' And that did n't go over well with many of those present . Then Roorda stood up and called for order . `` Excuse me , first of all , you do not tell me my function , '' said Alderman Terry Kennedy , who was chairing the committee that called the hearing . Things quickly got out of hand . On Thursday morning , Roorda told CNN he wore the wristband because `` I have a right to freedom of speech , expression , just as violent protesters in Ferguson , who attempted to kill and maim police every night . '' `` They were defended as exercising freedom of speech . ... I think I can wear a bracelet to a public meeting , '' Roorda said . French acknowledged Roorda 's rights but said his action did the opposite of trying to bring the community together . `` He showed it to the protesters in the front row . He tried to provoke a response . He succeeded , '' French said of Roorda . What triggered the scuffle depends on whom you ask . One witness , Cachet Currie , told CNN affiliate KMOV that Roorda , in trying to get to Kennedy , `` jumped out into the aisle and pushed me over . '' `` I got caught in whatever Roorda and Kennedy had going on , '' she said . `` I said , 'Wait a minute , do n't push me . ' '' The video shows some scuffling with a female . It does not show how the altercation started . Roorda said he was the victim . `` I tried to approach the podium and the anti-police radicals started pushing and shoving the police officers and myself , '' he said . The two sides then went at it . `` We went to protect her ( the woman ) and the police tried to protect him . And it was an all-out shoving match with some punches being thrown , too , '' said Robinson , the Ferguson preacher . After several minutes , the meeting was quickly adjourned . `` I think there were a few injuries but nothing serious , no ambulances called , '' Roorda said . `` We did n't see anyone get arrested . '' French , the bill 's sponsor , placed the blame on Roorda , calling his behavior `` deplorable . '' But he also bemoaned the tensions in the city . `` We saw once again tonight how fractured our city remains . We have a lot of work to do , '' he tweeted . `` I believe a strong civilian review board can help . '' CNN 's Michael Martinez contributed to this report .
