(Reuters) - A gunman was taken into custody after shooting a security guard at a gate outside the U.S. Census Bureau headquarters in Maryland on Thursday evening, officials said.
Emergency personnel were called to the scene in Suitland, Maryland, about 10 miles (6 km) from Washington, D.C., at about 6:30 p.m. local time.
The guard was shot in the upper body and taken to a local hospital in "extremely critical condition," said Mark Brady, spokesman for the Prince George's County Fire Department.
Brady said he did not know if the guard, an adult male, was a federal employee or a contractor.
The Washington D.C. Metropolitan Police Department tweeted that the gunman was later taken into custody. An officer was shot in the ankle during the incident, police said.
The Washington Post reported that the gunman had forced a woman into a green Honda before the initial shooting. The man then drove to the government building and shot the guard who approached the vehicle, the newspaper said citing D.C. Police Chief Cathy Lanier.
The Post said the suspect then fled the scene and led police on a chase through the city, which ended in a gunfight in which both the suspect and an officer were shot.
A representative for Prince George's County Police was not immediately available for comment.
In a statement on its Twitter account, the Census Bureau said there had been an "incident" at the Suitland Federal Center and there an investigation was underway.
"We are committed to the safety of all staff who work at the Census Bureau and are currently making sure that everyone is safe and secure," the statement said.
