ATHERTON, Calif. --Two Menlo College students were arrested Tuesday after they were allegedly seen stealing backpacks at a private high school, according to Atherton police. Raphael Daniel Bettan and Ryan Goodman, both 18, were arrested on suspicion of grand theft after a security guard saw them each take backpacks that were left unattended at Menlo School, Atherton police Sgt. Sherman Hall said. Menlo College and Menlo School are located on the same campus on Valparaiso Avenue, Hall said. Bettan and Goodman were seen picking up the unattended bags and taking them to a nearby grove of trees, Hall said. Security officers apprehended the suspects and called police. Two iPads and other electronic items believed to have been stolen were later found in the boys' dormitory, Hall said. Police are investigating whether Bettan and Goodman are responsible for other thefts that had recently been reported on campus, Hall said.
