GARDINER — A city man has been arrested on several felony charges after police allege he assaulted a 91-year-old relative.

David F. Dineen, 59, was arrested following an investigation into a report of elder abuse April 13 on Highland Avenue in Gardiner. He was charged with endangering the welfare of a dependent person, aggravated assault with a weapon, domestic violence assault and criminal threatening, all of which are felony-level charges, according to a news release Wednesday from Lt. Chris Read of the Kennebec County Sheriff’s Office.

Sheriff’s office Detective Brittany Johnson investigated the report of elder abuse and, with assistance from Gardiner police and Department of Health and Human Services agents, Dineen was arrested and charged that same day.

Read said the victim was a 91-year-old family member of Dineen’s. Read declined to say what Dineen allegedly did to the victim, or what sort of weapon was used in the alleged assault.

Dineen was later released from the Kennebec County jail in Augusta on $10,000 cash bail. Bail conditions include he have no contact with the victim or witnesses.

The Kennebec County Sheriff’s Office said any witnesses or anyone with information about the incident may contact police at 623-3614.

The news release noted Dineen has at least one prior conviction for domestic assault. In 2013, Dineen pleaded guilty to domestic violence assault after he was accused of attacking his then-girlfriend and mother of his child, leaving her with fractured ribs, a collapsed lung, bruises and a stab wound in her thigh.
