Man accused of committing lewd acts in view of drivers on I-95 in New Hampshire

A man was arrested after authorities say he engaged in inappropriate behavior in full view of other motorists while traveling on Interstate 95 in New Hampshire.

New Hampshire State Police announced Tuesday that Jonathan Ma, 27, of Portsmouth, has been charged with indecent exposure and indecency (subsequent offense) and violation-level negligent driving in connection with an incident that occurred in November 2025.

State police said officers identified the suspect as Ma after reporting that a man driving northbound on I-95 performed a sexual act on her on the afternoon of Monday, Nov. 24.

Following the investigation, troopers issued a warrant for Ma’s arrest and captured him at his home in Portsmouth on Saturday.

Investigators believe there were other unreported incidents involving Ma.

Anyone with information is asked to contact New Hampshire State Police Trooper Clark Brighton at Clark.A.Brighton@dos.nh.gov.

Ma was scheduled to appear in court on Monday.
