The head of the Portland Police Bureau's Professional Standards Division was arrested early Thursday on suspicion of intoxicated driving, police say.

Commander Steve Jones, who's been with the Bureau for 23 years, hit a telephone pole while driving a city vehicle on Southwest Third Avenue, according to Portland police. Jones was off-duty and traveling alone, police said. He wasn't injured.

The Oregon State Police cited Jones for driving under the influence of intoxicants and released him, as is standard practice for the agency in Multnomah County, according to Portland police.

Portland police said they asked the state police to process the investigation because of Jones' status as the Professional Standards Division commander. State police will continue the criminal investigation.

Jones is on paid administrative leave, as is standard procedure, pending the results of the investigation. Captain Jeff Bell will serve as the division's acting commander in Jones' absence.

An administrative investigation will be presented to the Police Review Board, which is made up of Bureau and community members.

"As law enforcement officers, we are held to a higher standard, regardless of rank or classification, that demands accountability," Chief Danielle Outlaw said in a statement. "This incident will be thoroughly investigated."

Portland police initially responded shortly before 2 a.m.
