The police report shows that Bieber claimed he was suffering from a hairline fracture in his right foot. He allegedly told officers he had injured his foot skateboarding three months earlier. Bieber appeared to sway and have leg tremors during one of the tests, but the injury was never mentioned or noticed after that test, the report said.
Bieber, who pleaded not guilty to his charges, also told officers he was not drag racing with R&B singer Khalil Amir Sharieff, who was driving a Ferrari when both were stopped. He also questioned why he was arrested in the first place.
When brought to the police station, Bieber was initially "agitated and condescending" and using profanity.
"He then got upset and said, 'I'm 19 years old. I'm just out having a good time,'" the report quoted him as saying. "What were you doing when you were 19?"
The officer replied that he was not driving around in a Lamborghini at that age.
"Yeah, well, I bet you didn't have millions of dollars in your bank account either," Bieber was quoted in reply.
The singer told officers that black Cadillac Escalade SUVs following the two sports cars were carrying security personnel and that the group was trying to avoid celebrity photographers who were tailing them.
He also mentioned taking an anti-anxiety medication whenever he feels "closed in," according to the report.
Police drug tests found the presence of the active ingredient in marijuana and Xanax, an anti-anxiety drug. Traces of alcohol were also detected with a breath test, but the level was below the 0.02 threshold considered intoxicated for drivers under age 21.
Bieber's trial date is May 5.
