Prince William County police seized an unspecified amount of cocaine and nearly 20 weapons, including several high-caliber guns and assault rifles, from a home in Haymarket this week, a bust that police think could link the suspect to a ring of drug dealers in the county.

Police arrested Christopher Perry, 22, of 1844 Ridge Rd., on Wednesday and charged him with possession with intent to distribute cocaine and manufacturing cocaine after a raid on his home yielded drugs, drug paraphernalia and 17 guns, according to officials. Police seized several revolvers, semiautomatic handguns, shotguns and two weapons similar to the M-16 and AK-47 military assault rifles, according to a search warrant filed in Prince William County Circuit Court.

Sgt. Kim Chinn, police spokeswoman, said police are continuing to investigate Perry and his associates. A police news conference scheduled for yesterday afternoon was postponed because the county's drug task force was investigating a similar case that could be linked to Perry's arrest.

"We believe this is part of a larger network," Chinn said yesterday.

Late last year, Perry was convicted of possession of cocaine, according to court records. He was placed on probation and his driver's license was revoked for six months, records show.

Perry was released on bond after his arrest Wednesday. Chinn declined to elaborate on the details of the case, adding that police plan to hold a news conference Monday afternoon to release additional information.
