Tiger Woods was sleeping at the wheel of his car and did not know where he was when he was arrested on Monday, according to police in Florida.
The American former world No 1 golfer was arrested on suspicion of driving under the influence with jail records showing he booked into Palm Beach County jail at 7:18am local time.
He was released at 10:50am on ‘his own recognisance’, meaning he has given a written undertaking to co-operate with future legal proceedings.
Woods later issued an apology in a statement, insisting it was nothing to do with alcohol, but rather was caused by an “unexpected reaction to prescribed medication”.
According to a police report released on Tuesday, Woods had “extremely slow and slurred speech” after being awoken by a police officer, who found the golfer’s car stopped in the right lane of the roadway and still running.
Police released a mugshot of Woods following his arrest in the town of Jupiter.
Woods’ statement read: “I understand the severity of what I did and I take full responsibility for my actions.
“I want the public to know that alcohol was not involved. What happened was an unexpected reaction to prescribed medications.
“I didn’t realise the mix of medications had affected me so strongly. I would like to apologise with all my heart to my family, friends and the fans. I expect more from myself too.
“I will do everything in my power to make sure this never happens again.”
The 41-year-old is one of the greatest golfers in history, with 79 career PGA Tour wins, but his career has been derailed by injury and issues away from the course.
He has not played competitive golf since pulling out of the Dubai Desert Classic in February after one round because of back pain.
The American subsequently had spinal fusion surgery on April 20, a fourth operation in three years on his troublesome back, which has limited him to three tournament starts worldwide in two years.
Woods was previously charged with careless driving outside his Florida home in 2009, as his personal life came under scrutiny, with the 14-time major winner admitting to having extra-marital affairs, issuing a public apology and planning to undergo therapy.
