Roberto Duran, former lightweight boxing champion, was arrested by Miami police after a routine traffic stop and charged with a felony for allegedly threatening “to beat up all American police officers,” a police spokesman said.

Duran became irate after the car in which he was riding was pulled over, police spokesman George Law said. Duran got out of the car, approached the officers and shouted profanities at them, Law said.

Duran held the lightweight title from 1972 to 1979 and the welterweight title in 1980. He now lives and trains in Miami.
