Police in Cedar Rapids, Iowa, have launched an investigation into the nightclub shooting that left two people dead and 10 injured.

The incident took place at 1:27 a.m. local time on Sunday at the Taboo Nightclub and Lounge in downtown Cedar Rapids.

Police “were able to respond immediately” to the reports of shots fired because they were on a routine patrol of the downtown area.

Following the shooting, two people were confirmed to be dead and about 10 people sustained injuries. Those who required treatment were transported to local hospitals to receive medical attention.

Police are in the process of interviewing witnesses and have not released information regarding the shooter or what may have caused the incident.

The club’s owner, Modteets Williams, Jr., told a local news outlet that his business was “doing everything we can to cooperate with police.” The club is believed to have hosted a 90s themed “Return of the Mac” party on Saturday night, according to social media promotions.

Following the shooting, Cedar Rapids Mayor Tiffany O’Donnell called for residents to take action to develop a safer community.

“Our hearts are with those impacted by the incident last night. This is not Cedar Rapids. This is not who we are. I want to thank our police officers for their swift response last night and their hard work every day keeping us safe,” O’Donnell said in a press release.

“The Cedar Rapids Police Department is working hard to bring the person or persons responsible to justice. As citizens, we can take an active role in heading off these incidents before they happen. This means respecting one another, resolving issues peacefully, and holding ourselves and each other accountable. Together we can build the safe and welcoming community we want for Cedar Rapids.”

The Cedar Rapids Police Department is asking anyone with information about the shooting to contact investigators.
