The Lowell Sun reports that Randy Meas made the allegation against Democratic state Rep. Rady Mom in a police report filed May 8.
Meas alleges Mom responded angrily after he tapped his shoulder to say hello. Meas says Mom grabbed his neck and choked him, and pressed a fist into his rib cage.
Meas wasn't injured but is seeking a harassment order against Mom in court on Thursday.
Mom hasn't been charged.
Mom is an acupuncture therapist who in 2014 became the first Cambodian-American elected to a U.S. state Legislature.
A message left by The Associated Press at his Statehouse office wasn't immediately returned.
