Former Melrose Place cougar Heather Locklear picked the wrong place for a meltdown this weekend.
The small-screen star was arrested around 5 p.m. Saturday after California Highway Patrol officers found her parked car blocking traffic in Montecito, Calif., a tony enclave near Santa Barbara.
According to the incident report, a "concerned citizen" called police after witnessing Locklear, 47, "driving forwards and backwards over a pair of sunglasses and revving her engine" in a parking lot.
The witness then came upon Locklear again on the road.
"The citizen became concerned when Ms. Locklear exited her vehicle and stumbled into the traffic lane...the citizen called 911 and reported the entire incident to CHP Ventura Dispatch."
When officers arrived Locklear appeared disoriented, per the report, and after giving her a sobriety test they determined she was not suffering the side effects of a booze binge.
"Although obvious impairment was exhibited during the tests, alcohol was ruled out as a factor," the CHP said in a statement. Locklear was arrested for suspicion of driving under the influence and taken to the Santa Barbara CHP office.
"She was evaluated by a drug recognition expert, who concluded Ms. Locklear was under the influence of a controlled substance, and could not safely operate a motor vehicle," CHP said in a statement.
Locklear's publicist declined to comment on the arrest.
The former Spin City fixture was booked at the Santa Barbara County Jail. She was released at 11 p.m. Saturday on $5,000 bail.
