Police say a 16-year-old boy threatened his sister, his mom and her boyfriend with a knife Thursday.
Officer Katie Flood said they were called to his family's apartment in the 2400 block South 10th Street at about 2 a.m. after he had gotten into an argument with his 11-year-old sister over a cigarette.
Flood said he got angry, got a knife from the kitchen and started walking around threatening everyone with it. She said he stabbed the floor and the couch and still had the knife in his hand when police arrived. After telling him several times to put it down, he did.
They took him to the Youth Detention Center, where he was lodged on terroristic threat allegations.
