Police: 5 at high school in Arizona accused of conspiring to kill another student on campus

Five students at a high school in Tucson are in custody for allegedly conspiring to kill another student on campus.

Tucson police say the five were arrested Wednesday night and booked into the Pima County Jail on suspicion to commit first-degree murder.

They say four of the five Flowing Wells High students are juveniles and their names are being withheld.

Police say officers went to the school Wednesday after another student told the Flowing Wells administrative staff of the alleged plan.

Detectives did interviews and learned that five students were involved in a week-long plan to kill another student they were having problems with and one of the five brought a knife to school.

Police say Flowing Wells administrative staff located that student and found a knife in his possession.
