AUGUSTA, Maine (AP) — About 550 ballots from Bangor that had been reported as missing were located and delivered to Augusta as the recount of Maine’s vote on an Oxford County casino continued into its fourth day.

On Tuesday, the recount focused on the ballots from Bangor and other ballots from small towns in southern Maine and Hancock County. Casino supporters have picked up a small number of votes as the recount progresses.

The recount was requested by casino foes after voters on Nov. 2 approved a statewide referendum by 4,601 votes allowing for Maine’s first casino with both table games and slot machines. Unofficial tallies put the margin at less than 1 percent of more than 564,000 votes cast statewide.

The recount is scheduled to resume on Friday.
