Philip Testa, the reputed leader of Philadelphia's organized-crime family, and his key associate, Frank (Chickie) Narducci, who is said by authorities to oversee the local mob's multimillion-dollar gambling operations, were among 10 men indicted here today on federal racketerring charges.

Testa, 56, who is said to have succeeded longtime boss Angelo Bruno after his gunshot murder in March, surrendered about 4 p.m. to federal officials. He was released on $40,000 bail.

The 29-page indictment alleged, in effect, that the 10 had participated in the business of organized crime, primarily loan-sharking and gambling.

The indictment's key allegations centered on a fake $175,000 robbery at the now-defunct Chestnut Hill Lincoln-Mercury dealership on April 16, 1975, almost six years ago, and gambling operations that it accused the mob of running between 1976 and 1978.

The other men indicted include Joseph (Chickie) Ciancaglini, 46, a former Teamsters union enforcer; Carl (Pappy) Ippolito, reputed to be gambler who divides his time between Florida and Bucks County; Harry (Junchback) Riccobene, 70, convicted on gambling and drug-supply charges, and his half-brother, Mario (Sonny) Riccobene, 48; Joseph Bongiovanni, 34, a former Philadelphia police officer who now works for a meat company; Charles Fred Warrington, who told the magistrate that he had earned his money "hustling around, gambling;" Pasquale Spirito, 41, and Frank Primerano, 42.
