A man who identified himself as the son of Sen. Rand Paul (R-Ky.) was arrested at the Charlotte Douglas International Airport on Saturday after a flight from Kentucky to North Carolina.

Police told reporters that William Hilton Paul, 19, was charged with underage drinking, disorderly conduct and being intoxicated and disruptive. He was held by the Mecklenburg County Sheriff's Office. 

“He was possibly served alcohol on the flight,” Charlotte-Mecklenburg Police Lt. Blake Hollar said. 

In a statement Sunday night, Paul spokeswoman Moira Bagley asked for the press to respect the family's privacy as they deal with the incident.

"Sen. Paul is a national public figure and subject to scrutiny in the public arena, however, as many parents with teenagers would understand, his family should be afforded the privacy and respect they deserve in a situation such as this," she said. 

Paul, the son of Rep. Ron Paul (R-Texas), was elected to office in 2010 and has expressed interest in a 2016 presidential bid.
