AUGUSTA, Maine -- Police say a disgruntled resident threw a cup of bedbugs at a general assistance counter in Maine Friday, forcing an immediate shutdown of the entire building."It was extremely shocking," Director of Development Services Matt Nazar told WMTW.Police said the man was unhappy with his housing."Our general assistance staff member initially thought it was coffee grounds that he had dumped on the counter," Nazar said. "And then some of the coffee grounds started moving."The workers immediately began scooping up and bagging the bugs."There were some that were crawling on the counter," Nazar said. "Some were dead. So there were well in excess of 100 live and dead bugs that some, like I said, were crawling away."Police said the man tried to leave, but officers stopped him outside in the parking lot.Pest control was called to treat the office and the rest of the building.On Monday, a bedbug detector was brought into the building to check the area before they opened it back up to the public.
