Toronto police say the robbery occurred at 1 p.m. on Nov. 22, 2014. It was a Saturday afternoon and the incident was caught on tape.
Police say an assailant approached a 25-year-old man from behind before assaulting him and taking his chain.
The victim tried to protect his daughter by holding her in his arms, as the robbery occurred.
The suspect left the mall and got into a red car. Police say two other people served as alleged "lookouts" in the robbery.
One of the alleged lookouts has been arrested — a 24-year-old Toronto man who faces a single count of robbery.
But police say they are still looking for a man they have identified as the "main suspect." They are urging 32-year-old Roland Nugent of Toronto to turn himself in. A warrant has been issued for his arrest.
They are also looking to locate and identify the second alleged lookout.
On Thursday, police released images of the two men they are trying to find. They also released a video of the robbery, which is posted at the bottom of this page.
None of the allegations made by police have been proven in court, nor have the charges against the accused.
Anyone with information is asked to contact investigators at 416-808-4300. Tips can also be passed on anonymously through Crime Stoppers at 416-222-8477.
