MERIDEN, Conn. (AP) – Federal agents and authorities from Massachusetts and Connecticut have arrested 16 men on drug and weapons charges in a regional crackdown of a nationwide motorcycle gang.

Keith Gallagher Sr., 50, was ordered held on $100,000 bail Thursday by a judge in Chicopee, Mass. Police say Gallagher is the national vice president of the California-based Diablos.

Gallagher was charged with possessing and trafficking cocaine in a school zone. Police say he sold more than 100 grams of the drug to an undercover police officer on several occasions. When he was arrested Wednesday, police say they found a sawed-off shotgun and marijuana in his Chicopee home.

Also arrested Wednesday night were 15 alleged members of the organization’s Connecticut chapter.

Authorities say the arrests resulted from a two-year state and federal investigation.

Eight of the Connecticut suspects face federal drug charges and were ordered held without bond pending hearings scheduled for next week in U.S. District Court in Bridgeport.

The seven other alleged gang members face state charges, including dispensing liquor without a permit, selling narcotics and illegally possessing firearms. Six of them were scheduled to appear in Waterbury Superior Court later this month; the seventh was ordered to appear in Meriden Superior Court on Dec. 20.

State police Sgt. J. Paul Vance said the arrests followed raids in Waterbury and Meriden that began Wednesday night and continued Thursday morning.

The Diablos once had their national headquarters in Meriden, and are now based in San Bernadino, Calif.

The gang has chapters in several other cities across the country.
