TACOMA, Wash. -

Police in Tacoma say two boys accused of carrying a pellet gun and brass knuckles as they followed another student have been expelled from a high school.

Police spokeswoman Loretta Cool says police who responded Wednesday morning to a call about a teen carrying a gun and walking across a field toward Lincoln High School classrooms found several students who started running away.

The News Tribune reports the spokeswoman says one of those boys had brass knuckles and another a pellet gun altered to look like a real firearm.

Police arrested the 16-year-old boy with the gun for investigation of felony harassment and bringing a dangerous weapon on school grounds. The 15-year-old boy with brass knuckles was arrested for investigation of bringing a dangerous weapon to school.
