Heather Locklear, 47, was arrested in Montecito on Saturday night. The police suspected her of driving under drug influence. She was arrested by the California Highway Patrol at about 7 p.m. because a citizen had called 911 saying that a woman was driving like she was out of her minds.

The actress, who is no longer in police custody, got into a car in Montecito parking on Saturday afternoon at about 4:30, as the citizen reported. Heather Locklear was acting strangely, driving back and forth over a pair of sunglasses on the pavement. Tom Marshall, a spokesman for the CHP, said that she stopped the car on the street and stumbled into the traffic.

The citizen who called 911 followed Locklear out of concern for her safe and for the other drivers. When the police arrived, the 47-year-old actress had parked the car on State Route 192, where she had blocked a lane. The officer who interrogated her said that she was disoriented and “under the influence of something.”

Tests at the police station showed that Heather Locklear wasn’t positive for alcohol and the drug tests will arrive in a few days.

The actress is known for her television work in roles as Sammy Jo Carrington in the soap opera “Dynasty” (1980) and Amanda Woodward in “Melrose Place” (1990). She also played in the sitcom “Spin City” as Caitlin Moore. She dated Tom Cruise, Ryan Ruddy, Mark Harmon and was married to Tommy Lee from 1986 to 1993. In 1997, she gave birth to Ava Elizabeth, whose father is Richie Sambora.

Locklear was treated for depression for 4 weeks until July 23, 2008. Her agent announced that she was suffering from anxiety and depression and she seems to haven’t passed the moment.
