Heather Locklear was arrested in Santa Barbara and booked on suspicion of driving under the influence - cops think she was on prescription meds.
The mug shot below is a fairly good indicator that something was amiss ...
A resident reported Heather was "driving erratically" while pulling out of a parking lot in Santa Barbara. The California Highway Patrol then found the former Melrose Place star's car parked on a state highway and blocking a lane of traffic.
After talking with her, the officer determined she was under the influence of something and arrested her. She was tested for drugs and alcohol.
Alcohol was found not to be a factor, but drug tests continue.
Heather Locklear was released without having to post bail. The cops probably just didn't want to have to stare at those creepy eyes any longer. Yikes.
