Police spokeswoman Gwendolyn Crump said late Thursday that the police department's internal affairs unit is investigating the incident.
On Tuesday, D.C. police used lights and sirens as they escorted the former "Two and a Half Men" star from Dulles International Airport to his stage show, "Violent Torpedo of Truth: Defeat Is Not an Option." At the time, Charlie Sheen was running nearly an hour late for the show.
Sheen tweeted about the ride and included a picture of a speedometer reaching about 80 mph.
Councilman Phil Mendleson says he met with D.C. Police Chief Cathy Lanier on Thursday. He says Lanier did not authorize the escort.
