Three Fullerton high schools were on lockdown Thursday as police investigated bomb threats.
The schools affected were Sunny Hills High School, 1801 Lancer Way; Troy High School, 2200 E. Dorothy Lane; and Fullerton Union High School, 201 E. Chapman Ave.
The first threat came in about 1:25 p.m. Thursday, followed by the other two, said Fullerton police Officer Kristy Wells.
The schools were locked down “as a precaution,” Wells said.
The public was encouraged to remain clear of the schools as police investigate, Wells said.
