"The man then fired several shots into the air -- When our officers heard the sound of gunfire, they immediately responded and were approaching the man when he shot himself," the statement said, noting that there were no other injuries.

"At this time, it does not appear the man was targeting any Members of Congress, who are on recess, and it does not appear officers fired their weapons.

"Our investigators are looking into the man's background. DC's Metropolitan Police Department is handling the death investigation," the statement added. — Agencies
