A former Lawrence, Massachusetts, police officer is facing charges for allegedly impersonating an officer in Londonderry. The incident began Sunday when a driver told police that an SUV ahead of them on Rockingham Road was traveling slowly. When the driver flashed their headlights, the SUV activated blue police lights and sped away. Police found the driver of that SUV in a parking lot and identified him as Mikel Beltran. Beltran told police he was a Lawrence police officer, but when Londonderry police contacted Lawrence PD, authorities said Beltran’s certification was suspended. Beltran was taken into custody.
