Tacoma police were called to an apartment for a disturbance early Tuesday morning in the 300 block of E. Wright Ave., said spokeswoman Loretta Cool.
As officers were approaching the apartment, they could hear people yelling and physically fighting from inside an apartment, Cool said. The front door was open and when officers arrived, they could see three adult men -- two men trying to hold off the other man.
Officers ordered the men to stop, but one man became verbally abusive toward the officers, then charged at one officer with his fists raised. The officer used a Taser to subdue the man and take him into custody, Cool said.
Afterward, officers could see into a back bedroom that the man's two sons had been injured. Investigators said they later determined the man had been in the front room with his two adult brothers and expected his sons to be asleep.
"When he went to check on kids and they were awake in back bedroom, he became very angry because they weren't sleeping yet," Cool said. "He choked both kids."
Cool said the 10-year-old tried to stop his dad from choking his younger brother but couldn't. One of the kids' uncles then came into the room and pulled the father off the 9-year-old.
Two other young girls and an infant were also in the home at the time of the incident. All were taken to Mary Bridge Hospital for treatment then placed with Child Protective Services as the mother was out of town, Cool said.
Cool noted the kids had signs of neglect and previous injuries but that investigation is still ongoing.
The boys' father was booked into jail for investigation of aggravated assault and resisting arrest.
