Retired race car driver Al Unser Jr. was arrested in Indiana early Monday and charged with operating a vehicle while intoxicated, authorities say.

According to a police report, the 57-year-old Unser was pulled over by police in Avon, west of Indianapolis, shortly after 1 a.m. after his vehicle was clocked going 59 miles per hour in a 45 mph zone and drifting from his driving lane. The officer who pulled Unser over said the driver was slurring his speech and his eyes were red and glossy.

Unser initially denied having anything to drink before staggering to the rear of the vehicle after exiting the car, losing his balance, falling to the ground and rolling down an embankment, the report said.

Blood was drawn from Unser after he refused to take a field sobriety test. Results were pending.

"At the police department, Unser Jr. complained about the tightness of the handcuffs on his wrists," the arresting officer, identified only as "J. Schwartz," wrote in the police report. "Tightness was checked multiple times and after continued complaints, I slightly loosened them further."

Unser again complained about the handcuffs as he was being taken to a hospital to have his blood drawn, the report said.

"I stopped my vehicle and checked for tightness again to find the tightness of the handcuffs appropriate," the officer wrote. "During my entire interaction with Unser Jr., he was consistently verbally hostile toward assisting officers and I."

The Harding Steinbrenner Racing team, for which Unser Jr. is a consultant, tweeted Monday that the "organization is saddened to learn of Al Unser Jr's arrest on an OWI charge. Alcoholism is a disease and a continuing battle for those struggling with it. At this time, we do support Al in any way that he needs."

INDYCAR and Indianapolis Motor Speedway also released a statement, saying "Al Jr. is loved by the racing community. Everyone at INDYCAR and Indianapolis Motor Speedway is with him and his family and stand ready to provide the support he needs."

Unser is the son of four-time Indy 500 winner Al Unser and the nephew of three-time Indy winner Bobby Unser. Unser Jr. competed in the Indianapolis 500 19 times, winning the race in 1994 and 1992. He also won two CART points titles and two IROC championships.

He was arrested in New Mexico in 2011 on drunken and reckless driving charges. Authorities in Albuquerque said Unser was driving more than 100 mph while drag racing against the driver of another vehicle.

Unser pleaded no contest to a charge of driving under the influence stemming from a January 2007 crash on a Nevada freeway. Nevada authorities said Unser's blood-alcohol content was three times the legal limit and he failed field sobriety tests. As part of the plea deal, Unser lost his driver's license for 90 days, was fined $1,000 and had to attend a drunken driving school, a victim-impact panel and undergo alcohol abuse evaluation.
