The Metropolitan Police Department and the Washington Field Office of the FBI investigated a suspicious letter sent to Anne Beers Elementary School in Southeast.
The letter tested negative for harmful substance. At this time, the FBI is connecting the incident today with suspicious letters received by two schools two weeks ago.
Shortly after 10 a.m. this morning, the elementary school at 3600 Alabama Ave. SE received an envelope filled with a powdery white substance. Metropolitan Police Department investigators and a hazmat team showed up to investigate.
Officials did not evacuate the school.
