La Mirada~The Sheriff's department received a telephone call from a 15 year-old boy early Tuesday evening threatening to harm himself.

Lieutenant Evans of the Norwalk Sheriff's Station told the La Mirada Blog they received a call from the boy shortly after 5 p.m. who said he had a knife and also wanted to be shot by police.

The boy was at Los Coyotes Middle School when he made the call. As officers were arriving, he made his way across the field and into the flood control channel, also carrying a backpack.

Parents and children conducting soccer practice on the school field observed officers running across the field.

Deputies caught up with the juvenille, with assistance from a sheriff's helicopter, north of the school at Behringer Park, where he was detained without incident behind the homes on Keating Drive.

The Lieutenant said he does not know why the boy was distraught and no other information is available at this time.
