PORTSMOUTH, Mass. — A man was arrested after authorities say he committed indecent acts in view of other drivers while traveling on Interstate 95 in New Hampshire.

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