D.C. police are investigating why actor Charlie Sheen received a police escort from an area airport to his show in downtown Washington this week.

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, 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 Mendelson says he met with D.C. Police Chief Cathy Lanier on Thursday. He says Lanier did not authorize the escort.
