Menlo-Atherton High School was put on lockdown this afternoon (Sept. 10) due to a threat to the school and a former student was arrested, Atherton police said. Someone called the police's tip line to let them know that a former M-A student had posted "concerning content" online about the school, according to a notice sent out by police. Police advised the school to lock down out of an abundance of caution.
