Police Allege This Woman Stole Homeless Man's Beloved Pet Rat

Police have released images of the woman who allegedly stole a beloved pet rat from a man experiencing homelessness in Sydney.

The rat, named Lucy, was taken from outside Footlocker on Pitt Street in the city's CBD earlier this month, while her owner Chris briefly used a nearby bathroom.

Notably distressed, Chris was later photographed sitting on a milk crate with a handwritten sign: 'My pet rat Lucy was stolen on Saturday. Lucy is black and white with a bit of brown.'

Sydney City Police Area and Command are appealing to the public for assistance after CCTV footage captured the woman they believe to be responsible.

Described as a woman of Caucasian appearance aged in her late 30s or early 40s with a slim build and curly brown hair, police say she approached Chris's belongings before walking away with Lucy on April 6.

She is shown wearing a cream coloured sweater over a yellow shirt and blue shorts over 'muscle' print tights.

Lucy is a well-known city fixture who is even trained to kiss people who regularly stop to take photos with her.

She was often seen sleeping on a blue blanket and munching on food while Chris chatted with those passing by.

Since her theft, an online campaign to retrieve Lucy has gone viral.

"Almost everyday since I started my job in the city Chris & his pet rat Lucy have sat in the same spot," a GoFundMe page raising funds for Chris reads.

"Taking a homeless persons loved pet -- seriously, what a really low act."

The page has so far raised $729, which in the event Lucy isn't returned will be used to give Chris the opportunity to find a new companion.
