A woman was assaulted by her “on and off boyfriend” after walking in on him performing oral sex on another woman in a bedroom in the couple’s Florida home, police report.

Richard Chancey, 50, was arrested around 4 AM yesterday and booked into jail on a misdemeanor domestic violence charge. He remains locked up in lieu of $1000 bond, according to jail records.

Responding to a 911 call, a Sebastian Police Department officer interviewed Sharon Lisovich, who said that she “began yelling at Richard and arguing with him” after discovering her beau “performing oral sex” on another woman, who is only identified as Angelika in the police report.

As they argued, Lisovich recalled, Chancey struck her in the face with “an open fist.” Angelika confirmed Lisovich’s account of being hit by Chancey, but she “refused to advise on anything further.”
