A homeless man tied up Manteca police, firefighters and emergency medical technicians as well PG&E crews on Monday afternoon for more than three hours. He also cost the owner of the Sinclair gas station in the 1000 block of East Yosemite east of Powers Avenue more than three hours of business. The man — who was trespassing — refused to come down from the roof of the convenience store. While it might have been novel to onlookers snapping photos with smartphones behind police tape as well as those that had pulled out folding chairs to watch the situation unfold, it was old hat for first responders. Such incidents happen throughout the year. Retired police chief Charlie Halford who now serves as a councilman, noted homeless on roofs was an issue back in the 1970s when he first started with the department.
