R.A. Brown Middle School and Ladd Acres Elementary School in Hillsboro, Ore., were on lockout Tuesday morning after five explosive devices — the equivalent of what a police official called a science class experiment — were found in a skate park near the schools.
Students were in classes when a Hillsboro parks employee found the first of the five plastic bottles containing a corrosive liquid at 9:25 a.m., officials said.
The top of that bottle popped and the incident was initially reported as an “explosion,” Hillsboro Police spokesman Lt. Henry Reimann said, adding that neither the parks employee nor anyone else was injured.
Reimann said the five plastic bottles were found in a variety of locations at the Reedville Skate Park at Southeast Frances Street and Cornelius Pass Road.
