Carmine Cervellino allegedly stabbed the watermelon and left it in the kitchen for a woman to see. The woman thought it was a "menacing gesture" and called police, the Register Citizen reported.
After the woman spotted the stabbed melon, Cervillino entered the room and began silently slicing pieces of the punctured fruit.
Thomaston Officer Keith Koval wrote that the alleged victim thought the 49-year-old was using "passive aggressive" tactics to "intimidate her because he is angry at her."
Earlier this month, the woman alerted police about marijuana and pills that she had found stashed in Cervellino's tool box.
The items were never recovered and Cervillino is not looking at any drug charges.
