Passenger Daniel Drinan arrested for watching pornography and fondling himself on board Denver flight

A 63 year old man was reported to flight attendants when he was seen viewing poography and touching himself on board an airplane.

Daniel Michael Drinan was seen using the airline's WiFi inteet service to view po on his laptop by other passengers on the flight.

One passenger alerted a male flight attendant, who went to investigate and found the suspect's genitalia exposed.

According to a U.S. Attoey's Office media release, the flight attendant told Drinan to 'put his pants back together'.

He was taken into custody on Saturday night at Denver Inteational Airport on charges of committing lewd, indecent or obscene acts in public aboard an aircraft.

Drinan had tried to use his laptop at times to hide his activity, investigators added.

The Federal Bureau of Investigation and the Denver Police Department are investigating the case, with Assistant U.S. Attoey James Allison in charge of the prosecution, according to the Justice Department.

A spokesman for Southwest Airlines told the Denver Post that Southwest does have filter restrictions in place for what is viewable through the airline's WiFi but that filters by themselves are not always a guarantee.

If convicted, Drinan could be sentenced to 90 days in jail and ordered to pay a $250 fine.
