A man in his fifties pretended to be a customer and entered a gold store on Castle Peak Road at 2.19 pm. When an employee showed another customer a gold chain worth about HK40,000, he immediately snatched it and fled.

The staff called for the police, and officers later found the robber headed towards an industrial building on Un Chau Street.

Officers tracked down the man, saw him attempting to hide on the roof of the building and arrested him.

The man was remanded in police custody.
