WEST HARTFORD, CONN., NOV. 9 -- Alphonse (Allie Boy) Persico, the reputed former head of the Colombo organized crime family in New York, was arrested here today by the U.S. Marshals Service, federal authorities said.

Persico, a fugitive since 1980 when he failed to appear for sentencing on an extortion conviction in connection with alleged loan-sharking activity, was tracked down by U.S. marshals and taken into custody at a West Hartford apartment, U.S. Attorney Stanley A. Twardy said.

Twardy would not reveal where Persico was being held, except to say that he was in Connecticut.

Persico, who had been on the FBI's list of its 10 most-wanted fugitives, is scheduled to appear Tuesday in U.S. District Court in Hartford, Twardy said.

"The government will ask that he be held without bond because of his fugitive past," Twardy said.

The marshals service said seven deputy U.S. marshals followed a trail of phony identification and aliases to the apartment, where Persico had $7,000 in cash in his possession when he was arrested about 5:30 p.m.

Persico, 57, was the reputed head of the Colombo family before fleeing on June 20, 1980, according to Laura Brevetti, who is assistant attorney-in-charge at the Justice Department's Organized Crime Strike Force offices in Brooklyn, N.Y.

Persico's brother, Carmine, subsequently took over the family leadership position, Brevetti said.

Persico previously had been convicted of murder and served 17 years of a 20-year sentence.

His criminal record dates back to 1949 with charges of assault, murder, fraud, false statements on bank loans, firearms violations, extortion and possession of stolen property.
