WASHINGTON — Cleveland Cavaliers guard Delonte West was indicted Tuesday on additional weapons and traffic charges stemming from his Sept. 17 arrest for speeding on a motorcycle and carrying multiple weapons.

The eight-count indictment sheds no new light on why West, 26, was riding a motorcycle on the Capital Beltway in Prince George’s County, Md., at 10 p.m. with two loaded handguns and a loaded shotgun. Prosecutors on Wednesday added an 8 1/2-inch Bowie knife to the list of concealed weapons West was carrying.

It’s illegal in Maryland to carry concealed weapons and to transport loaded handguns.

West was indicted on two counts of carrying a dangerous weapon, two counts of carrying a handgun, two counts of transporting a handgun, and one count each of reckless driving and negligent driving. The charges are all misdemeanors. Each weapons count carries a penalty of up to three years in prison.

West was initially charged with just two counts of carrying a handgun and with driving in excess of reasonable and prudent speed.
