The woman that Lindsay Lohan was chasing just prior to her arrest for driving under the influence and possession of cocaine has been revealed to be the mother of her former assistant Tarin Graham.

What's more, it seems that her mother was so scared of what Lindsay would do to her if she caught up with her that she called the police on the emergency 911 number...and now the recording of the conversation she had with the operator has appeared online!

Graham had just quit Lindsay's employment, and had her mother come and pick her up to take her away from where Lindsay was abusing alcohol again.

According to police Lindsay was driving a 2004 Yukon that didn't belong to her, and was in hot pursuit of the 2007 Escalade being driven by the mother of Lohan's former personal assistant,.

Lohan was accompanied by two men who were not arrested.
