CHICAGO (AP) _ A man accused of killing a former New York state senator was arrested a few hours after he was featured a second time on the television show ''America's Most Wanted.''

Arthur Everett Flournoy, 52, formerly of the Brooklyn borough of New York City, was arrested by the FBI and city police late Friday at a Chicago apartment where he had been living. A federal warrant charged him with unlawful flight to avoid prosecution on New York murder charges, the FBI said.

Flournoy, a retired New York City corrections officer, is accused of fatally shooting Vander L. Beatty on Aug. 30, 1990, in the victim's storefront campaign office in Brooklyn. Beatty was running for a party committee seat in the Democratic state primary.

The shooting occurred after a judge refused to reduce Flournoy's alimony and child support payments at a hearing where he was represented by a lawyer Beatty recommended, said New York police detective Lt. Peter Tartaglia.

The lawyer, Harry Pollak, said Flournoy was angry and punched him after the court hearing, The New York Times reported Sunday. Beatty was shot to death 45 minutes later.

Beatty, 49, and a college classmate of Flournoy's, spent more than 20 years in politics and was trying to make a comeback after serving prison time for racketeering, tax evasion and election fraud, the Times said.

''America's Most Wanted'' profiles criminals at large and investigators asked the show to include Flournoy.

Flournoy was first profiled Nov. 9, 1990. That broadcast yielded 104 tips, the show's spokesman, Jack Breslin, said from Washington, D.C., where the show is based.

The second time, Friday night, produced 61 tips, 12 in the Chicago area, Breslin said.

FBI agents and Chicago police subsequently showed Flournoy's photograph to his Chicago landlord, and Flournoy was arrested, Breslin said.

Flournoy remained in police custody late Saturday after a judge denied bond, Breslin said.

A hearing to extradite Flournoy to New York was set for Monday, Tartaglia said.

Chicago and New York police could provide no further details.

Flournoy is the 147th fugitive to be captured as a result of profiles on ''America's Most Wanted'' since its debut in February 1988, Breslin said. The show is broadcast on Fox TV and syndicated.
