SAN DIEGO (CNS) - A Poway man who allegedly holed up in his home along with his ex-girlfriend -- against whom he had a restraining order -- and fired off a gun after a raucous fight between the two prompted a law enforcement response was behind bars Thursday and facing a slate of criminal charges.

Bryon Edward Henry, 33, was arrested Wednesday night following a 90- minute standoff, according to sheriff's officials.

Deputies were sent to the suspect's house in the 13000 block of Utopia Road about 7:30 p.m. on a report that Henry was allegedly behaving in a threatening manner toward a former romantic partner, Lt. Christopher Collier said.

When the patrol personnel tried to make contact with him, Henry retreated into his residence along with the woman, 31-year-old Kiera Genesta, and refused repeated orders to exit and surrender, the lieutenant alleged.

As deputies tried in vain to persuade the suspect to give himself up, gunshots sounded inside the home, according to Collier.

Authorities evacuated several nearby residences as a precaution during the fraught encounter, the lieutenant said.

Eventually, Genesta walked out of her former boyfriend's home and was taken into custody on suspicion of violating a court order. A short time later, deputies took Henry into custody.

No one was injured during the standoff, Collier said.

Henry was booked into San Diego Central Jail on suspicion of resisting arrest, making criminal threats, negligently discharging a firearm and inflicting cruelty on a child. The reason for the latter charge was not immediately clear.

Henry was being held on $100,000 bail pending arraignment, scheduled for Friday afternoon.
