A Newton man has been indicted by a federal grand jury for allegedly making repeated sexual contact with a 17-year-old girl aboard a flight to Boston, according to the U.S. Attorney’s Office.

Jonathan Alan Lefman, 46, allegedly touched the girl who was seated in front of him onboard a flight from Puerto Rico to Boston last August. Lefman was reportedly with his wife and four children at the time.

He was indicted on one count of abusive sexual contact while in the special aircraft jurisdiction of the U.S. Lefman was previously arrested on Feb. 7 on a criminal complaint and released on conditions.

According to the feds, Lefman was a passenger aboard a JetBlue flight flying from San Juan, Puerto Rico to Boston with his wife and four children last Aug. 30.

On multiple occasions during the flight and while on the ground waiting to deplane in Boston, Lefman allegedly engaged in abusive sexual contact with the girl.

“Specifically, it is alleged that Lefman intentionally worked his hand in between and through the area between the back and bottom of the seat directly in front of him, where the minor victim was seated, and touched the minor victim’s buttocks without her permission,” the U.S. Attorney’s Office wrote.

“On at least one occasion when he did so, the minor victim saw his reflection leaning between the seats in the seatback monitor in front of her,” the feds added. “On the last occasion when he allegedly touched or attempted to touch her buttocks, the minor victim was able to use her cell phone camera to take a video of Lefman’s fingers protruding between the back and bottom of the minor victim’s seat.”

The girl took a video of Lefman as he got off the plane, according to court documents.

After deplaning, the minor victim’s adult female family member who had been traveling in a different row reported Lefman’s alleged conduct to a JetBlue supervisor and confronted Lefman — showing the video of his fingers.
