- Federal investigators are looking into a "potential criminal act" onboard an American Airlines Flight.
- One passenger told local news that a woman on the plane suspected a camera had been put in the bathroom.
- A police trooper said it involved "a juvenile, a phone, and a flight attendant."
The FBI and Massachusetts State Police are investigating a "potential criminal act" onboard an American Airlines flight from Charlotte, North Carolina to Boston on Saturday, the police announced.
The authorities didn't provide details about what may have occurred, but local news station Boston 25 reported that it concerned a passenger alleging that there was a camera hidden in the plane's bathroom.
A trooper with the police unit that responded to the incident told another local outlet, WSOC-TV, that it involved "a juvenile, a phone, and a flight attendant."
A passenger on the flight from Charlotte, North Carolina to Boston told Boston 25 that a male flight attendant stopped a teenage girl from entering the bathroom, saying he needed to wash his hands. She used the bathroom after him, the outlet reported.
The girl's mother was then seen stopping other passengers from using the bathroom, and warning them there was a hidden camera inside, the passenger told Boston 25.
When the Airbus A321 landed at Boston Logan International Airport around 10 a.m., the passenger said police and airline staff checked the bathroom, before the flight attendant was escorted off.
The Massachusetts State Police confirmed in its statement that its officers met the plane upon landing and initiated an investigation. It added that potential crimes that occur mid-flight are the responsibility of federal authorities, who asserted their jurisdiction over Saturday's incident.
In a statement to the news stations, American Airlines said: "American Airlines flight 1441 from Charlotte (CLT) to Boston (BOS) was met by law enforcement upon arrival. We take this matter very seriously and are fully cooperating with law enforcement in their investigation, as safety and security are our highest priorities."
