PHOENIX (AP) - Phoenix police are trying to figure out why a man reportedly got on a bus, rode it to a school and left a gun magazine with 15 rounds of ammunition on the bus.
Authorities say the man told an adult bus assistant he was with a boy who had also just boarded the Alhambra Elementary School District bus on Thursday.
The man got off the bus but police were called when a child found the magazine.
Officers say they later determined that the man approached the boy in his neighborhood Wednesday but was rebuffed.
Police arrested 29-year-old Jeremy West after getting tips when news broadcasts reported a description of the man on the bus.
West is charged with endangerment, criminal trespass and having a weapon on a school property.
