On June 18th, park dispatch broadcast a “be on the lookout” message for a man with a hammer who was threatening a school group at China Beach. Numerous Park Police officers responded. The first officer to arrive identified the man and attempted to arrest him, but the man evaded and resisted and it took additional officers to get him cuffed. A hammer was recovered from his person. Other officers spoke with the teacher and a chaperone accompanying the school group. They reported that the man, apparently homeless and mentally ill, had approached the group on the beach and made angry and inappropriate comments to them. He then picked up and threw rocks in a threatening manner and made additional angry and inappropriate comments to the school children. When the teachers asked him to move away, he pulled a hammer out of his bag and brandished it at them in an aggressive manner while walking away. The man was arrested and issued mandatory appearance citations for engaging in threatening behavior, committing physically threatening acts, and resisting a police officer.
