A Vietnamese businessman who was arrested after hiding from two criminal charges last year has been slapped with an additional charge for “abuse of positions and powers while on duty,” investigative police announced Wednesday.

Phan Van Anh Vu, aka Vu ‘Nhom,' fled his residence in the central city of Da Nang to hide in Singapore after the Security Investigation Agency under the Ministry of Public Security issued a warrant for him on December 21, 2017.

The business tycoon, known for owning different companies and multiple pieces of ‘prime real estate’ in Da Nang, was later deported for violating Singapore’s immigration regulations.

He was arrested upon landing in Hanoi on January 4.

Police later commenced criminal proceedings against the 43-year-old businessman accused of “deliberately disclosing state secrets” and “tax evasion,” the Security Investigation Agency confirmed at a press conference on Wednesday.

Officers said at the same meeting that they had also filed an additional charge for “abuse of positions and powers while on duty” against Vu ‘Nhom’ and planned to hold him in custody for four months pending further investigation.

The probe is being conducted to verify alleged criminal activity perpetrated by Vu and any associated organizations and individuals in trading publicly-owned land and houses in Da Nang and other cities and provinces, according to the investigation agency.

Born in 1975, Phan Van Anh Vu is a business tycoon owning various companies, including I.V.C Co. Ltd., 79 JSC and Bac Nam 79 JSC as well as his stake in several other entities such as Seaprodex and DongA Bank.

The agency would not elaborate on why a business mogul now faces charges related to “state secrets” and “abuse of powers.”
