LEWISTON — Police continued to crack down on those suspected of illegally carrying firearms over the weekend as part of an ongoing effort to eliminate gunfire in the residential downtown.

Early Saturday morning, police said, two juveniles found with firearms were charged with carrying concealed weapons. Those charges follow the arrest of seven other youths who were charged on Friday in connection to a violent assault captured in a video that went viral on social media.

The seven charged on Friday were taken to the Long Creek Youth Development Center in South Portland. The two charged on Saturday were released with conditions that they refrain from further criminal conduct. Those two were additionally charged with receiving stolen property.

Later Saturday night, police on foot patrol recovered another firearm at Pine and Howard streets, this time from a woman who was charged with carrying a concealed weapon.

Police said 21-year-old Juma Amino of Lewiston was also charged with providing liquor to a minor, unlawful drug furnishing, refusing to submit to arrest and failure to inform police of a concealed handgun.

Then on Sunday, 18-year-old Didi Djodjo of Portland was found on Bartlett Street with a gun that had been reported stolen, police said. Djodjo was charged with carrying a concealed weapon, refusing to submit to arrest, falsifying physical evidence and possession of stolen property.

In the wake of a wave of gunfire within the city, police in Lewiston have been bolstering patrols with extra officers, including some federal agents who work out of the new police station.

Police Chief Carly Conley on Friday said that she would use whatever manpower and technology she has at her disposal to crackdown on gunfire and violence within the city.

“The men and women of the department are aware of the impact these incidents have on local residents and their feelings of safety,” the chief said. “The department is committed to using all resources to address these issues for our residents.”

Police said more officers will be seen on the streets, but also that efforts are being made “behind the scenes” to combat the problems.
