JUPITER ISLAND, Fla. ? Prosecutors in Florida moved this week to subpoena Tiger Woods' prescription drug records, widening the legal battle around the DUI case that followed his March rollover crash.

According to The Associated Press, prosecutors are seeking records from a Palm Beach pharmacy covering prescriptions filled from the beginning of the year through the end of March, including dosage information and any warnings about driving impairment.

The subpoena request comes after AP's initial arrest report said deputies found Woods at the crash scene with two pain pills in his pocket, observed signs of impairment and arrested him after he refused a urine test even though he passed a breathalyzer exam.

Woods later said he would seek treatment and step away from public golf duties, according to AP's follow-up on his plea, which also said he entered a not guilty plea while preparing to miss the Masters.

The pharmacy records, if obtained, could become a central part of the state's effort to explain what substances may have been in Woods' system at the time of the crash.
