Police looking into the cause of Tiger Woods’ car crash say they have concluded their investigation – but are unable to release the findings without the 15-time major winner’s permission.

Woods was released from hospital earlier this month after sustaining a number of serious injuries when his SUV overturned in Los Angeles on February 23.

The 45-year-old was the sole occupant in his vehicle which struck a median strip, rolled and came to a rest on its side near a steep road.

“We have the contents of the black box, everything completed, signed, sealed and delivered but we cannot release it without the permission of the people involved in the collision.”

Following the crash, Woods had a rod inserted in his right tibia, with additional screws and pins inserted into bones in his foot and ankle.

He is now recovering at his home in Florida.

Villanueva, who was speaking in a Q&A posted to his Instagram account, added: “It still remains an accident.

“Nothing has changed on what we learned from the course of the investigation. Everything we did turned out to be accurate.”
