Six children and three adults received injuries during the attack that occurred Saturday night, the local CBS affiliate reported.
Nine people were injured, some seriously, in a violent stabbing spree in Boise, Idaho, on Saturday night.
Timmy Kinner was asked to leave an apartment complex in Boise, Idaho this week after poor behavior and left peacefully.
Police say Kinner returned on Saturday, when the girl was having her party a few doors down from where he had stayed.
"We haven't had anything involving this amount of victims in a single act in Boise in the history of the department". Boise Police Chief William Bones held a news conference and said the victims were some of the newest members of the community. All of the victims have been hospitalized, and according to CNN, four sustained life-threatening injuries. However, the woman realized the arrangement was not working and asked Kinner to leave Friday. "The suspect is in custody and being interviewed at this time", the Boise Police Department said on its Twitter feed.

Protesters chanted "shame!" and sang "shut detention down!" at the kickoff of a New York City march Saturday. There were also marches in more conservative regions like Wyoming and Kansas, and in cities large and small.
Investigators said they do not know yet if the suspect was connected to the victims in any way.
Bones fought back tears as he revealed the ages of the injured children: There had been a 3-year-old, two 4-year-olds, a 6-year-old, an 8-year-old and a 12-year-old "from different continents" gathered that night to celebrate a child's birthday, he said.
A resident of the complex had recently met Kinner, who was new to the area and needed a place to stay, Bones said. "Please keep them and their families in your thoughts and prayers".
Police closed roughly a mile of the road during the initial investigation and later rerouted traffic to the lanes farthest from the complex using flares and barricades. "We must come together to condemn this vile act".
Timmy Kinner, 30, of Los Angeles, was arrested on nine felony charges of aggravated battery and six felony charges of injury to a child.
Officials with the Boise branch of the International Rescue Committee told the Statesman they're planning a vigil for Monday evening, though details on time and place are yet to be determined. Some people posted on Facebook that they planned to take flowers to the complex Sunday.
