ARLINGTON, Wash. -- An "emergency situation" forced the evacuation of Arlington High School in western Washington on Tuesday.
A message sent to parents said it appeared that a "homemade smoke device" was set off in a bathroom around 8:30 a.m. The school went into lockdown, but all students and staff were safe.
Parents were asked not to come to campus during the situation, and the Arlington School District said students who normally take the bus were transported to Haller Middle School.
Students who normally walk or drive will be released for the day once attendance is taken.
There was no reported damage, and classes are scheduled to resume normally Wednesday.
