WESTPORT — A Trumbull resident violated a protective order in sending multiple Facebook messages to a victim, police said.

In October, a victim reported receiving multiple private Facebook messages from Karen Backus, 54, using a third person’s account, police said. At the time of Backus’ messages, Backus was under a protective order that stipulated she not have any contact with the victim, police said.

The investigating officer learned Backus used a friend’s phone to send the victim messages without the phone owner’s permission, police said. Police received a warrant to arrest Backus, who turned herself in on the active warrant on June 9. She was charged with criminal violation of a protective order and released after posting $20,000 bond. Backus was scheduled to appear in state Superior Court in Norwalk on June 11.
