The 42-year-old woman was attacked by more than a dozen people at about 2am on Sunday near Mirador Mansion in Tsim Sha Tsui. After snatching her handbag with cash, the robbers immediately scattered.

Police said they received a report from a passerby that a woman was attacked by a group of men at the junction of Nathan Road and Carnarvon Road, and robbed of a handbag containing about HK$600,000 in cash and a mobile phone worth about HK$10,000.

It was understood that the money was medical fees for the woman's grandson.

Police searched for the suspects in the area and launched a pursuit, arresting three African men aged 37 to 42 at the junction of Carnarvon Road and Bristol Ave. But the police did not find the lost money, believing it was taken by others in the gang.

Suspecting that the robbers had run into Mirador Mansion, the police deployed a large number of officers to search inside the building, but nothing suspicious was detected.

The female victim suffered back and elbow injuries, and was taken to Queen Elizabeth Hospital for treatment.

The case was referred to the Yau Tsim Police District for follow-up and the other men were wanted.
