A private security guard was charged yesterday with stealing $12,000 worth of audio-visual equipment from the U.S. office building he was assigned to guard over the Thanksgiving weekend.

Assistant U.S. Attorney Charles H. Roistacher said the charge was filed against Gary Greene, 22, of 6321 Landover Rd., Landover, Md., after a search warrant was executed Monday night.

Greene, who said in court records that he was a security supervisor for Ensec Security Guard Co., was assigned the night of Nov. 27 at the Equal Employment Opportunity Commission offices at 2401 E St. NW, according to court documents.

The next day, EEOC officials reported to police that numerous pieces of government-owned video recording gear worth $12,000 apparently had been stolen.

According to an affidavit filed by D.C. Police Det. William F. Gately Jr., Greene told an informant that the property was at his sister's apartment at 5100 F St. SE.

The informant told Gately on Monday night that he had seen similar property in that apartment and the Greene had offered to sell it to him for $6,000, according to the affidavit.

Greene also said he was planning to move the property to New York City that same night, according to the affidavit. Police then got the search warrant and arrested Greene.

Greene was released yesterday on personal bond after the formal filing of charges of theft of government property.
