A Crofton man said yesterday that two men who he said were Anne Arundel County detectives forced him into a car Friday night and threatened to kill him if he didn't reveal the whereabouts of his brother, who is wanted on charges of assaulting a county police officer.

Michael C. Rogers, 21, said that the men confronted him in the parking lot of a High's store on Connecticut Avenue in Kensington. Once inside the car, Rogers said, the men put a gun to his head and threatened to kill him if he didn't tell them where they could find Harold D. Rogers, 24, who overpowered and abducted a female police officer who was escorting him to jail Aug. 28.

Rogers said he recognized the two as Anne Arundel detectives who had interviewed him about the escape several weeks ago.

A Montgomery County police spokesman said officers responded to a report about 8:30 p.m. Friday of a man being forced into a blue Pontiac and driven away from the store. They did not pursue the investigation because the victim has not made a formal complaint, the spokesman said.

Sgt. Joseph H. Bisesi, an Anne Arundel police spokesman, said he did not know of such an incident. He said that if a complaint is made to the department, it would be investigated by the internal affairs unit.

Harold Rogers was arrested last month by Anne Arundel police on a felony theft charge. After his arraignment in Annapolis, he was being driven to jail by Officer Janice J. Schwartz, who had handcuffed him with his hands in front and allowed him to ride in the front seat.

Police say Harold Rogers struck Schwartz in the face, hit her head against a window, took her gun and ordered her to drive to Crofton, where a woman got into the car. Schwartz later was set free.

Michael Rogers said he was questioned at his home two weeks ago by two detectives. He said they were the same men who forced him into the car Friday night.

Rogers said that after leaving the High's store Friday night, he was approached by a man who didn't identify himself. The man threw him against a wall and said they were going for a ride, Rogers said. A second man walked up and forced him into a dark blue car, he said.

Rogers said one of the men put a gun to his head and told him he would kill him if he didn't reveal his brother's whereabouts. The men drove him to the parking lot of the Kensington library, but left after seeing other cars there. They then took him to a school parking lot and to other places, saying they were looking for a secluded spot, he said.

Rogers said that an hour later, the men drove him back to the store, where, he said, he saw two Montgomery County police cars. Rogers said he was told by the two men that they would shoot him on the spot if he said anything.
