Used syringes and needles make an impromptu but quite frightening weapon.

In Brisbane, Australia, a woman has been arrested having used such a weapon in a string of alleged robberies. Maree Sharelle Leighton, 41, has been charged with nine offences including armed robbery in company, acts intended to cause grievous bodily harm or transmit serious disease and stealing.

Police will allege Leighton’s offending occurred across the south-east last week including Waterford West, Post Office Square and at Roma Street, Brisbane. Police allege Leighton armed herself with a syringe and robbed her victims at ATMs and inflicted a needle stick injury on a victim at Roma St. During all of the alleged offences handbags, purses, cash, credit cards and personal identification were stolen.
