The final fugitive indicted in the 1976 bombing assassination of former Chilean Ambassador Orlando Letelier was arrested Tuesday, FBI officials said.

Virgilio Paz Romero, 39, who allegedly detonated the bomb, had been living quietly in nearby Lake Worth as a landscaper, said William Gavin, head of the FBI in Miami. He said the arrest apparently stemmed from a story about the case on last week's "America's Most Wanted" television show."The arrest went extremely smoothly. Paz said he was happy to be out of fugitive status," said Gavin.

U.S. Magistrate Ann Vitunac ordered Paz held without bond pending a further hearing Friday, said FBI spokesman Paul Miller.

Paz was the last man at large to be named in a 1978 indictment for aiding the Chilean secret police agency DINA in bombing Letelier's car, killing the former ambassador and his aide Ronni Moffitt.

Letelier was ambassador to the United States at the time of the 1973 right-wing military coup that killed President Salvador Allende and quickly became the leading critic of the new regime.
