A WITCH told a traffic cop she was above the law because she was "from another world" before dragging him at high speed down a busy street.

"Your laws and penalties don't apply to me. I'm not accepting them, I'm sorry, I must go, thank you," Eilish De Avalon said, before driving off with Sen-Constable Andrew Logan’s arm caught in her driver's side door, the Geelong Advertiser reports.

The officer was left seriously injured in the incident after being dragged nearly 200m.

De Avalon, who also told police she "had a universal name that is not recognised here", pleaded guilty in the Geelong Magistrates’ Court to recklessly causing serious injury, dangerous driving and driving while suspended, using a mobile phone while driving and failing to stop on police request on February 23.

The court heard the officer feared for his life when De Avalon drove off at high speed with his right arm pinned in her car window.

Sen-Constable Lamb said De Avalon ignored repeated calls to stop and instead accelerated, reaching up to 60km/h as she dragged Leading Senior Constable Andrew Logan along busy Moorabool St, in Geelong.

She stopped only after being forced to slow in traffic and the officer grabbed the keys from her ignition.

De Avalon, 40, a marriage celebrant who is also a self-confessed witch from the Geelong suburb of Highton, had initially been stopped after she was seen using a mobile phone.

"When asked to produce her driver's licence, De Avalon replied that she did not have one," Sen-Constable Lamb said.

"When asked why not, she said, 'I'm a being from another world and don't require one.' When asked to state her name and address De Avalon replied, 'I have a universal name that is not recognised here'."

Sen-Constable Lamb said that when asked for ID, De Avalon said, "Your laws and penalties don't apply to me. I'm not accepting them, I'm sorry, I must go, thank you.

"De Avalon began to wind her window up and Sen-Const Logan reached through in an attempt to remove the keys from her ignition. She continued to wind the window up pinning the officer's right arm to the door frame.

"She then drove off dragging him along with her."

The policeman suffered serious injuries to his right arm, shoulder and chest and is expected to undergo further surgery.
