SALINA – Law enforcement authorities in Saline County are investigating a report of a 12-year-old boy threatening 3 children on a school playground.

Just after 5:30 p.m. on Tuesday, police officers were sent to the Schilling Elementary School playground in Salina when parents reported a boy chased three children with a brown handled knife with a 4-inch blade, according to Salina Police Captain Mike Sweeney.

The boy also allegedly threatened to stab the children if they did not leave the playground.

After police learned his identity, the boy was taken into custody at his home.

Charges of aggravated assault and criminal threats are being requested. He is being held at the juvenile detention center in Junction City

Sweeney said officers dealt with the same boy just before 3p.m. on Tuesday when police responded to a report about a student with a gun on a school bus.

The bus was stopped at Target and officers found the boy had a 4″ long toy, cap rifle.

Police took the toy gun from the boy and contacted his mother to take him home.

There are no charges requested in connection with the incident on the bus.
