A Danbury man has been arrested on home invasion and kidnapping charges.  Police were called to a disturbance at a home late Tuesday night and learned that 32-year-old Francisco Fontanez-Trinidad forced his way inside.  He allegedly assaulted a man, brandished a pistol and threatened the victim.  When the man resisted, Police say Fontanez-Trinidad discharged the pistol and assaulted the man with the gun.  A woman was forcibly removed from the residence and made to drive to Fontanez-Trinidad's home.  During the drive, Police say he repeatedly assaulted the woman, leaving visible signs of injury.  About an hour later, Fontanez-Trinidad called police about what he had done and asked police to come to his Bennett Place home.  He was arrested without incident and the pistol was recovered.  Fontanez-Trinidad was also charged with Unlawful Discharge of a Firearm, Disorderly Conduct, Assault, Threatening, and Reckless Endangerment.
