A 29-year-old man who was arrested for a 450 million yen (US4.2 million) heist early this month in Tsim Sha Tsui, Kowloon, has been linked to terrorism and a jailbreak in India.

Ramanjit Singh, alias Romi, who was born in India and studied in Hong Kong, had been the subject of a Red Notice issued by the International Police Organization (Interpol) as he was accused of committing a list of crimes including attempted murder, robbery, harboring offenders, raising funds for terrorist acts, among others, according to Interpol’s website.

Indian media said police had received an alert that Singh had been arrested in connection with a robbery in Hong Kong and would initiate the process for his extradition.

But the Hong Kong Police Force refused to comment on whether any person on Interpol’s wanted list was being detained in the city, Ming Pao Daily reported.

Singh is now being held in Lai Chi Kok Reception Center in Kowloon.

Singh was arrested in 2016 in India and later released on bail. He jumped bail and escaped to Hong Kong but allegedly masterminded the Nabha jailbreak in Punjab state, according to The Tribune.

It was believed that Singh set up a “control room” in a subdivided apartment in To Kwa Wan, Kowloon, to coordinate the movement of the escaped prisoners using Internet telephony. which made it difficult for the police to track down, Sing Pao reported.

Singh and five others were arrested after they allegedly attacked a group of five employees of a currency exchange in Chungking Mansions in Tsim Sha Tsui while they were carrying two suitcases containing 450 million yen to a bank on February 9.

Police arrested Singh and two other suspects and recovered the money the same day. Three other suspects were arrested on February 21.
