Both directions of I-15 were closed in Clearfield during rush hour Monday evening while police negotiated with a man who walked onto the freeway median and pointed a gun at himself, Utah Highway Patrol said. The man was eventually taken into custody with minor injuries after nearly four hours, officials said. The incident began Monday afternoon when police were investigating a crash and pedestrians let them know about a man who was standing on a freeway off-ramp and acting suspiciously, Utah Highway Patrol Sgt. Nick Street said. When police approached the man, he held a gun to his head and didn't obey officers' commands, Street said. The man started to walk up an off-ramp and onto the freeway median, Street said. The UHP's Special Emergency Response Team was called to help negotiate with the man.
