The internet has been up in arms since videos of a 69-year-old doctor getting dragged off a United Airlines flight from Chicago went viral on Monday.
The man, whom TMZ has now identified as Dr. David Dao, was asked to leave United Flight 3411 to Louisville due to overbooking after a computer chose him at random.
But the doctor refused to get off the plane because he had to treat patients the following morning and needed to get home, according to a passenger.
Security officers then grabbed Dr. Dao, causing him to hit his head on a metal armrest, before dragging him off the plane.
The incident caused an uproar online and prompted a statement from United Airlines CEO Oscar Munoz, who claimed they had good reason to remove the “disruptive and belligerent" passenger:
“This situation was unfortunately compounded when one of the passengers we politely asked to deplane refused and it became necessary to contact Chicago Aviation Security Officers to help.”
There was initially very little information on Dr. Dao's identity, but now new details are emerging.
And some of them appear to reveal a dark past...
According to The Daily Mail, Dr. Dao specializes in internal medicine in Kentucky. His wife and four of his five children are also doctors.
But the grandfather's track record isn't exactly pristine.
In 2005, the doctor was charged for exchanging drug prescription for sex, resulting in 98 felony counts of “illegally prescribing and trafficking painkillers,” according to TMZ.
He also received five years probation for six counts of illegally obtaining drugs.
Dr. Dao, who obtained a medical degree in his home country of Vietnam before moving to the U.S., was forced to surrender his medical license following the charges.
But the suspension was lifted in 2015, and he is now legally able to practice medicine at an outpatient facility one day a week, according to The Hollywood Life.
Despite the shocking revelations about his past, many social media users are standing by the 69-year-old. Some Twitter users wrote:
Dr. Dao has yet to speak out publicly about the United Airlines incident.
Update 4/12/17: United Airlines CEO Oscar Munoz has formally apologized for the incident.
