Rocker Tommy Lee’s helicopter pilot was questioned over suspicion of California DUI following a flying incident where he flew too close to a police helicopter Sunday morning and failed to obey instructions from a traffic control tower. Los Angeles police were dispatched to the Van Nuys Airport but could not locate the pilot. He was later found at a bar, claiming he had been drinking after he landed. The police released the pilot after asking him to perform a field sobriety test and submit to a chemical test for blood alcohol content.

The Federal Aviation Administration will decide what action needs to be taken after the results of the toxicology test are finalized.

Lee, the drummer for Motley Crue was on board the helicopter at the time, though he was not a subject in the investigation.
