MIAMI (AP) _ Two more striking UPS employees have been arrested in the stabbing of Rod Carter, a former linebacker for the University of Miami and a UPS driver who crossed the picket line, bringing to six the number of men charged in the attack, police said Wednesday.

Carter was stopped at a red light in his delivery truck last Thursday when he was attacked and stabbed five times. Carter was a starter on the Hurricanes' 1987 national championship team.

Marcelo Rodriguez, 27, of Hialeah, was arrested Tuesday and charged with aggravated battery and being a principal in the crime. Werner Haechler, 32, of Miami, is charged with aggravated battery. Both men were released Wednesday after posting bail.

Four other UPS drivers had already been arrested in the incident. Charged with attempted first-degree murder were Benigno Rojas, 28, of Hialeah; Orestes Espinosa, 20, Pembroke Pines; and Angel Mielgo, 30, of Hialeah. Adrian Paez, 25, of Hialeah, was charged with aggravated battery.

All but Rojas had been released on bond Wednesday, according to the Metro-Dade Corrections Department.

Carter, 31, was treated at a hospital for stab wounds to his torso and back and was released.

Carter was drafted by the Dallas Cowboys in the 10th round in 1989, but he was cut and returned to his native Fort Lauderdale.

He became a guidance counselor and coached football at several South Florida high schools. He said he became a UPS driver four years ago, primarily for better pay and long-range career opportunities.
