ACT Police arrested a 32-year-old Ainslie woman on Thursday in connection with a ram-raid on Monday morning. She was allegedly in possession of drugs when arrested.

The ram-raid happened in Garran at 3.45am on Monday, when a stolen Toyota Celica was allegedly used to force entry to a liquor store.

A cash register, 18 bottles of liquor and 477 packets of cigarettes were allegedly stolen.

On Thursday afternoon police found the woman in a Phillip shopping centre, and arrested her. A subsequent search allegedly found bags of methamphetamines, cocaine and heroin.

The woman is facing court on charges of aggravated burglary, three counts of possessing a drug of dependence, and breach of good behaviour obligations.
