An Indian-origin man has been arrested for allegedly molesting a 22-year-old woman who was sleeping beside him on board a Spirit Airlines flight from Las Vegas to Detroit. The woman has accused 34-year-old Prabhu Ramamoorthy of shoving his fingers inside her pants ‘and vigorously moving them’.

The woman on the window seat noticed that both her shirt and pants has been undone. She said that the accused stopped touching her when she opened her eyes, Dailymail reported.

According to the complaint cited by CBS Detroit, the shaken passenger immediately informed the flight attendant about the alleged assault.

Wayne County Airport Authority took Ramamoorthy into custody when the flight landed at Detroit Metro Airport.

He had initially stated that he had been in ‘deep sleep’ during the flight and did not know where he had placed his hands. He later told an FBI agent that he might have unhooked the sleeping stranger’s bra ‘while playing with it’ and had cupped her breasts over her blouse.

Ramamoorthy also admitted that he ‘unzipped the woman’s pants part-way and put his finger in her pants’ in an attempt to digitally penetrate her, but was ultimately unsuccessful, the court filing stated.

He appeared for a preliminary hearing in US District Court in Detroit and was remanded to jail. The detention hearing was scheduled for Thursday afternoon.
