Police are searching four people who staged a HK$10 million (US$1.27 million) robbery in Tsim Sha Tsui in Kowloon on Wednesday evening.

At 7:30pm, three staff members from a money-changer were carrying two suitcases loaded with cash and about to get into a seven-seater car outside the Far East Mansion on Middle Road, three people approached then and one hit one staff member with a glass bottle, the Oriental Daily reported.

The two others grabbed the suitcases containing HK$10 million in cash from the boot of the vehicle. The three then ran to Nathan Road and got into a car carrying a fake license plate, according to police.

A 26-year-old employee of the money-changer suffered a head injury and was sent to Queen Elizabeth Hospital for treatment. He was in stable condition.

Chan Ka-ying, the acting chief inspector of Yau Tsim Police District, said the cash belonged to a money-changer in the Far East Mansion and had just been collected by the three staff members who were sent by another money-changer. The two money-changers were doing business together.

Chan said the suspects included one Chinese man and two South Asians, but police did not yet know the identity of the driver. Officers were checking surveillance camera footage around the area, but no arrests had been made.

It was the second high profile robbery in Tsim Sha Tsui in six months.

In February, five men working for a money-changer in Chungking Mansions were robbed of two suitcases which carried more than 400 million Japanese yen (HK$32 million) on Nathan Road. Police later arrested six men and recovered the money.
