A man on a stolen scooter packing a gun full of ammunition tried to ram one of the cops who had pulled him over on a sidewalk early Thursday, only to have the officer step aside at the last minute, sending the guy and his passenger flying onto the asphalt after the scooter jumped the curb and spun out of control, police say.

Kyvon Ross, 25, of Dorchester, now faces multiple firearms and motor-vehicle charges, the Boston Police Department reports.

Police say officers on patrol in the area of Washington Street and Columbia Road shortly before 1:20 a.m. "when they observed a moped scooter without a license plate traveling at a high rate of speed on Washington St. towards Erie St."

Both driver and passenger had their hoodies up and ski masks over their faces, but no helmets, police say:

"Officers changed their direction of travel and observed the moped turn right onto Erie St. and left onto the wrong way of Greenwood St. Officers drove down Greenwood St. and came to a stop at the intersection of Greenwood St. and Ellington St. near a driveway the moped drove down.

"Officers exited their police cruiser and approached the moped in an attempt to speak with the operator, later identified as Kyvon Ross, but as soon as Officers exited their vehicle, Ross accelerated his scooter at a high rate of speed towards one of the Officers. The Officer was able to move out of the way of the scooter, and Ross drove the scooter off a sidewalk curb causing him to lose control and both occupants falling to the ground.

"Officers detained the rear passenger of the scooter without incident, but Ross immediately began to violently resist. During the attempt to detain Ross, Officers felt the handle of a firearm protruding from his waistband. Ross continued to resist and attempted to remove an Officer’s hand from the firearm inside his waistband and a struggle ensued. Backup Officers arrived and Ross was eventually placed in custody. "

Police identified the gun, with an obliterated serial number, as "a Glock 22 with a flashlight attachment, loaded with thirteen rounds of 40 caliber ammunition in the fifteen round magazine, and one round of 40 caliber ammunition in the chamber."

Ross was charged with illegal possession of a firearm, illegal possession of a loaded firearm, possession of a large-capacity firearm, possession of a firearm with a defaced serial numb while committing a felony, illegal possession of ammunition, unlicensed operation, reckless operation, receiving a stolen vehicle and resisting arrest, police say.

Police add two officers suffered injuries during the fracas, one serious enough to warrant transportation to a local hospital, although his injuries were not life threatening.
