The force said on Saturday that the latest arrest had taken place on Friday and involved a 61-year-old man suspected of stealing 10 million Vietnamese dong, or about HK$3,060 (US$390), in cash from another passenger on a flight from Ho Chi Minh City.
The alleged victim had discovered his overhead bag had been taken and found the cash inside was missing after recovering his luggage.
Police officers were called and they arrested the 61-year-old man after retrieving the missing cash from his luggage.
The suspect was still in custody as of Sunday. The force’s Lantau criminal investigation unit is following up on the case.
Officers also arrested a 38-year-old man on Wednesday last week for allegedly stealing US$4,500 from another passenger’s overhead bag on a flight from Da Nang.
