Months after leaving a treatment facility, Heather Locklear was arrested on suspicion of driving under the influence of a controlled substance Saturday afternoon in Montecito, police said.

According to the The Associated Press , the Melrose Place star was pulled over by the California Highway Patrol after a resident reported the actress was "driving erratically."

When questioned, Locklear appeared to "be under the influence of something," a patrol spokesman said.

After being tested for alcohol and drugs, the 47-year-old was booked at 7 pm on suspicion of driving under the influence of prescription medication. She was subsequently released.

Locklear, who was treated for anxiety and depression earlier this year, has yet to comment on the incident. - Adam Bryant
