June 23, 5:02 a.m.: A worker at a construction site on Arsenal Street spotted a man walking around inside the fence who did not appear to belong.

When he was being booked, Police found that the man had a ziplock bag with what appeared to be methamphetamine. Robert Richards, 34, homeless, was arrested for trespassing, possession of a Class A drug, and the warrants.
