Perez was arrested Saturday after an accidental shooting, Marcos Grunfeld reports.
Perez was reportedly handing a gun that he owned to pitching coach Cesar Quintero, when the gun went off -- Quintero was shot and didn't survive the incident. The accident occurred in Venezuela, and the 26-year-old pitcher is cooperating with police. Pitchers and catchers reports Feb. 13 for Chicago, so it's unclear if Perez will be in attendance Tuesday.
