(WPRI) -- A Fall River couple was in the right place at the right time Friday night, stopping to help a woman and her 4-year-old son as they were attacked by their neighbor's PIT BULL.
Police said the victims' were familiar with the dog and its owner, living next door on Bay Street in Fall River.
A police report reveals the dog's owner was not home at the time of the attack, but his mother was. She told police the woman and her children asked to feed the dog some treats.
Police said the owner's mother opened the gate, and when the boy went to give the dog the treat, it lunged at his face.
Kaylin and Marco Arruda were driving down the street. around 8 p.m. Friday when they heard screams for help.
"I literally didn't even put the car in park, and I jumped out and started running over," Kaylin Arruda said. "That's when we saw the dog attacking the mother."
"Bit her right in the head and he was just tearing her head apart," Marco Arruda said. "She was just screaming, 'Help me, help me, help me.'"
By the time the Arrudas arrived, the young boy had already been attacked by the dog.
"It was absolutely horrible to see," Kaylin Arruda said.
The Arrudas said they kicked the dog several times and hit it with a rake, but it continued to attack the woman.
Police said the attack went on for several minutes, until Fall River Police Officer Tyler Andrade arrived and "used force" to kill the pit bull. "He went up to the dog and he put his gun up to his neck and he shot him twice in the neck," Marco Arruda said. "He had no choice, the dog had a hold of her head. I'm sorry, he had no choice."
"That officer was, he's the one who was completely the hero here," Kaylin Arruda added.
The woman was then rushed to Rhode Island Hospital, and her son was taken to Hasbro Children's Hospital. Police said they both suffered serious, but non-life threatening facial injuries.
Kaylin Arruda said she has been in touch with the woman, who told her that her son underwent facial reconstruction surgery Saturday night and is still in the Intensive Care Unit.
While police were at the scene Friday, the dog owner's brother was arrested Friday night after the attack.
According to the police report, Aaron Rego was walking aggressively on Bay Street towards the scene while the victims were still lying on the ground awaiting an ambulance.
Police said Rego started questioning officers about who shot the dog. According to police, he ignored officers' commands to stay back and calm down.
Officers on scene reported smelling alcohol on Rego's breath. Police informed Rego that he was under arrest, but he resisted.
Police said an officer threatened to use a stun gun on Rego if he didn't stop resisting. He was eventually placed in handcuffs and taken into custody.
Rego is charged with disorderly conduct, resisting arrest and interfering with a police officer. He was held at the Fall River Police Department Friday night and is due in court Monday.
It's unclear if the dog's owner will face any charges at this time.
