After kicking and punching Gil and causing "serious injury to the head and face," all three were arrested and charged with assault.Arroyo tok off his seven mounts at Belmont Saturday after being held in custody. According to the Post, Gil's sister, Aura Lausell, said her brother was severely injured. "They hit him all over," she told the Post. "He looked like a monster -- his face looked terrible."Arroyo, who was narrowly defeated in the Eclipse voting as leading apprentice rider last year, won 188 races from 1,165 mounts, earning $6.9 million. But he also was suspended six times, according to the Post, and fined $500 for throwing punches at a security guard at Saratoga.
