Police say man shoots himself fatally outside NY City Hall

Police say a man is dead after he drove up to a gate outside New York's City Hall and shot himself in the head.
A police spokesman says the man drove a black sedan up to the east gate of City Hall at 7:30 a.m. (local time) and shot himself.
His name was not released. There were no other injuries.
Manhattan-bound traffic on the Brooklyn Bridge was suspended while police investigated the shooting, causing rush-hour traffic backups on both sides of the bridge.
The man shot himself close to one of two main security checkpoints for all people entering City Hall. Members of the public must pass through a metal detector before entering the building.

Security was tightened after a gunman killed a City Councilman in 2003.
