SIDNEY — A Biddeford man faces charges that he drove around drunk with his 4-year-old son in the car’s passenger seat, police said.

The man, Tony A. Leland, 46, of 4 White Tail Drive, Biddeford, was pulled over by a sheriff’s deputy Friday night on Middle Road in Sidney. He registered a blood-alcohol content that was more than three times the legal limit, said Kennebec County Sheriff Randall Liberty.

Liberty said they were lucky to stop Leland before anyone got hurt.

Police received a report at 8:13 p.m. Friday of an erratic driver in Sidney. Deputy Michael Dutil located the 1995 Saab on Middle Road and pulled it over because one of its headlights was out.

Dutil noticed a bottle of alcohol between the two front seats and that the driver appeared intoxicated, according to a police affidavit filed in court.

Leland failed a field sobriety test and his blood-alcohol content registered at 0.26 percent, according to Liberty. The legal limit for driving is 0.08 percent.

“We also found him in possession of Oxycontin; we found four pills on him that were not prescribed to him,” Liberty said.

He said police did not determine where Leland had begun driving. Leland’s son was released into the custody of an uncle and grandfather.

Police charged Leland with unlawful possession of a scheduled drug, endangering the welfare of a child, operating under the influence and violating conditions of release.

Leland had been out on bail on a prior charge of OUI in southern Maine, Liberty said. The latest OUI charge is Leland’s third, he said.

Leland made his initial court appearance Monday and was being held at the Kennebec County Jail in Augusta on $5,000 cash bail, according to a jail official.
