A man, said to be angry about child support rulings, was shot dead while brandishing an inert hand grenade in the new federal courthouse in Seattle, Washington state, police said.
Hundreds of judges, jurors, employees and prisoners in the 23-storey building were evacuated and surrounding streets were cordoned off as dozens of police cars responded.
Officers could not tell that “what appeared to be a Second World War-type of grenade” was inert until after the shooting, Police Chief Gil Kerlikowske said.
The man, dressed in camouflage, was identified in newspaper and television reports as Perry Manley, 52, of Seattle.
