It now appears that there were some shady circumstances surrounding Heather Locklear’s DUI arrest. TMZ is reporting that the person who called 911 was former Us Weekly staffer Jill Ishkanian who was under investigation by the FBI.

When Heather got in her car, Ishkanian called 911, even though the car wasn’t even moving at the time.

Now get this — sources say immediately after Ishkanian called 911, she called a paparazzi agency to give them the heads up Heather was about to be popped. TMZ obtained those photos, not knowing it was Ishkanian who set the ball in motion.

And it gets worse. Ishkanian apparently is the only witness who says Lockelear was driving erratically and that she was drunk, even though it’s already established she was not under the influence of alcohol.

Is that crazy or what? Police reports indicate that Heather was not drunk but judging by the looks of her mugshot she was definitely under the influence of something.

Heather Locklear was arrested on suspicion of driving under the influence of a controlled substance in the upscale Santa Barbara area. Tests are being conducted to determine if she was on prescription medication. The actress recently completed a stay in rehab at an Arizona medical facility to fight anxiety and depression.

TMZ Reports:

A resident reported Heather was “driving erratically” while pulling out of a parking lot. The California Highway Patrol then found Locklear’s car parked on a state highway and blocking a lane. After talking with her, the officer determined she was under the influence of something and arrested her.

She was tested for drugs and alcohol. As we first reported, law enforcement tells us alcohol was not a factor. They are conducting drug tests.

Locklear was later released on her own recognizance, without having to post bail.
