ATLANTIC CITY — A city teen was arrested Saturday and police recovered a loaded handgun after officers responded to a ShotSpotter alert. Police responded to the 300 block of Arctic Avenue after the city’s gunshot-detection system registered an alert, according to police. Officer Kevin Perez obtained information about the suspect’s description, and Officer Eric Knuttel quickly located Malik Lyons, 18, police said. Lyons fled as Knuttel approached him but was later apprehended on North Carolina Terrace. Police said Perez found a loaded handgun hidden near where Lyons was initially spotted and where he ran from the officer. Lyons was charged with unlawful possession of a weapon, obstruction of justice, and certain persons not to possess a weapon, police said. He was sent to the Atlantic County jail.
