The man then went into the Royal Kitchen, where he entered then left several times before making his move.
At one point, he even appeared to look into the woman's purse on the back of the wheelchair.
"At first he says 'No, I don't want anything I'm just checking out the prices.' Then when he was ready to lift the handbag, he made a purchase. He went forward, paid for it and quickly lifted the bag," said Benn.
After taking the purse, the man doesn't even leave right away, instead he waits for his change.
Once the man disappears the elderly woman realized she had been ripped off.
"She was upset, she knew her handbag was missing. It was a shock to her," said Benn.
Benn said the suspected purse-snatcher was spotted at the Chinese Cultural Plaza later that night, but police were unable to arrest him because he did not have any of the woman's belongings on him.
She hopes the video will lead to his arrest and also encourage others to take preventative action to protect their belongings.
