A witness said a marked police SUV was heading south on Connecticut Avenue NW with its lights and siren on when it collided with a male pedestrian crossing west to east on L Street.
“The impact was huge,” said Joan Maher, a nurse from Bethesda who witnessed the crash.
The impact sent the police vehicle into the concrete median and flower bed just south of the intersection at Farragut North. The intersection remains closed to traffic.
Maher didn’t know whether the traffic signal was red or the pedestrian had a walk signal.
Washington Post reporter Clarence Williams tweeted at the scene of the crash:
