INDIANAPOLIS IMPD is investigating after shots were fired at the Castleton Square Mall on Monday night.Indianapolis Metropolitan Police Department North District officers responded to the Castleton Square Mall, located at 6020 E 82nd St., at 8:30 p.m. on reports of shots fired.Off-duty officers working for Simon Malls responded within seconds. The mall was quickly secured, and shoppers were safely evacuated, IMPD says.No injuries were originally reported, but a short time later, an adult male victim arrived at Eskenazi Hospital suffering from a gunshot injury. The victim was reported to be in stable condition. IMPD says the victim was shot during the incident at the mall. An 18-year-old male was arrested for felony intimidation with a deadly weapon for his alleged role in the incident. Police said he was arrested just a few hours after the shooting.Police believe all individuals involved were known to each other and were involved in a disturbance before the shooting occurred. There is no threat to the community at this time, however it is an active investigation. Detectives continue to work to hold other involved individuals accountable. Just think about how traumatic this was for families. These individuals involved resorted to using gun violence again for their conflict resolution and that does not work, IMPD Officer Tommy Thompson said. These people put others at risk and that is not tolerable.Anyone with any information is encouraged to contact Detective Christopher Williams at [email protected] or (317)327-3475. Alternatively, they may contact Crime Stoppers at 317-262-TIPS. Callers can remain anonymous.
