Authorities investigating a bomb threat at the District Court in Hyattsville determined that the threat was false, according to Hyattsville police.
The building at 4990 Rhode Island Ave. was initially evacuated when the threat was made to a court clerk in a phone call around 12:35 p.m., but those who evacuated have since been able to re-enter the building , said Sgt. Chris Purvis, a city police spokesman.
Northbound and southbound lanes on Rhode Island Avenue, which were shut down after the report came in, have also been reopened, Purvis said.
Purvis said K-9 units from the Prince George’s police department, sheriff’s department and University of Maryland police department, were called in to search the building for any signs of explosives but the search didn’t turn up anything.
He said the caller who reported the false threat is currently unknown.
The District Court building was shut down and investigated for more than two hours before reopening shortly after 3 p.m.
