A Northeast Washington man who claims a 4th District police officer stole $1,000 from him during a June 16 raid on his home refused to testify yesterday before a federal grand jury investigating allegations that some 4th District vice officers kept money and drugs seized during raids.

Anthony B. Fultz invoked Fifth Amendment protection against self-incrimination when he was questioned by Assistant U.S. Attorney Charles Harkins, who said he would seek an order compelling Fultz to testify under a grant of immunity.

In court papers seeking dismissal of charges against Fultz, his attorney, Allan M. Palmer, claimed that 4th District Officer Shelton D. Roberts took Fultz's $1,000 and filed reports showing that only $24 was seized. Roberts is considered to be a subject of the current police corruption probe.

As a result of the June 16 raid, during which police seized nearly $250,000 worth of heroin, crack, cocaine and marijuana, Fultz was charged in a four-count indictment with possession and intent to distribute cocaine and heroin, and possession of marijuana. The cocaine charge carries a mandatory minimum prison sentence of five years.

Fultz's case was dismissed by the government after disclosure of an FBI undercover investigation of the 4th District vice squad and the FBI's seizure of most of the squad's records. The U.S. attorney's office has said it will drop more than 300 cases because they may be tainted by police misconduct. Prosecutors have indicated they may be able to refile some of the cases.

Fultz has said other people had access to the apartment, and prosecutors want to question him about them, sources say.
