Police noticed the bulges on their hips as they fled. Zone 1 officers were able to detain two of the males, with one being a juvenile carrying a firearm. Officers spotted the third male run into a home on Atmore Street.
SWAT was called out of an abundance of caution. Police conducted a search of the home, and the suspect was not located.
