Guillaume Sebastien Roger Mattler, a 48-year-old French national, has been charged with abusive sexual contact following an incident on a Swiss International Air Lines flight from Zurich, Switzerland, to Miami, Florida, on Tuesday. The victim, a 29-year-old woman, was seated next to him in the first-class section when witnesses reported seeing Mattler inappropriately touching her as she slept. One passenger filmed the incident, while another alerted a flight attendant. When confronted, Mattler was found with his hand on the woman's crotch over her jeans. After being moved to economy class, he attempted to hand the woman a note complimenting her appearance while sleeping. Despite initially denying any wrongdoing, he later admitted to touching her but downplayed the severity of his actions. Mattler appeared in a Miami federal court and has a pre-trial detention hearing scheduled for Monday.
