When Massachusetts State Police responded, they found Jorge Zambrano, known to have an extensive criminal record, and his girlfriend.

Court documents allege that Zambrano threatened troopers, who used pepper spray to calm him down during the arrest.

Zambrano’s girlfriend then posted $500 to free him.
