"Around 4:30 p.m., a female witness saw Heather Locklear driving erratically while leaving a parking lot in Montecito. The witness said Locklear was revving her engine loudly, and backed over a pair of sunglasses several times," People magazine quoted him as saying.
He further said that the Double Tap actress seemed to be "disoriented and impaired", when she was found seated in a vehicle, which was almost blocking the way. "When a CHP officer arrived, Locklear was found seated inside her vehicle, which was partially blocking the roadway," he added.
Marshal said that Locklear co-operated a lot while being administered drug and alcohol tests "Alcohol was ruled out as a factor, but based on the officer''s observations, we believe Locklear was under the influence of prescription medication," Marshall said.
Locklear booked at a local jail in the evening, and was released hours later. Her lawyer Blair Berk was not available for comment, while her publicist had no comment.
