A Napa man was arrested after he supposedly beat up his girlfriend, destroyed her phone and endangered her child on the 2000 block of Patton Avenue on Monday, according to Napa Police.

Jason Taylor Dunne, 30, and his girlfriend were in an argument in their shared home when she locked herself in a bedroom. Dunne then forced the bedroom door open, confronted her and punched her in the face, causing her to lose consciousness, police said.

Afterward, she grabbed her 1-year-old child who was present during the altercation and went to the garage. Dunne followed, arguing with the alleged victim and bit her in the face while she was still holding the child, police said.

The victim had visible injuries to her face, police said.

When she told Dunne she was calling 911, Dunne allegedly grabbed her phone from her and threw it down, destroying it. The alleged victim’s pitbull defended her and attacked Dunne, allowing her to flee to a neighbor’s and call the police, police said.

Dunne was not at the residence when police arrived. Residents reported seeing a suspicious person, bleeding and covered in weeds, running down the street at about 5:30 p.m. Dunne was located by police on the 2100 block of Patton Avenue waiting for an Uber driver to pick him up.

Dunne had two outstanding warrants out for his arrest and is on probation in Napa County.

He was arrested and booked at the Napa County jail on suspicion of assault, battery causing serious bodily injury, injuring wireless communication, child endangerment, probation violations and for the warrants.
