Vanhelleputtet is the fourth employee of Uganda's telecom giant to be deported in the last one month after being declared prohibited immigrants.
The director Criminal Investigations Directorate (CID), Grace Akullo confirmed Vanhelleputte's deportation to Belgium without giving details. She instead referred our reporter to police spokesperson Fred Enanga for details.
MTN staff deported earlier include Italian national Elsa Mussolini, the former general manager for mobile finance services, French national, Olivier Pentout and Rwandan national, Annie Bilenge Tabura.
So far only Mussolini has spoken out about her deportation, saying she was ejected from the country for allegedly inciting violence by funding Robert Kyagulanyi alias Bobi Wine, the Kyandondo East MP and People Power architect.
There has however been an ongoing investigation against more MTN staff for allegedly compromising national security using their positions at the company.
The staff members being investigated as part of a classified investigation have since recorded statements with the Special Investigations Unit (SIU) in Kireka.
The investigations began in July 2018 after the Internal Security Organisation (ISO) raided their call center in Mutundwe a Kampala suburb and removed servers.
According to a reliable source in security circles, government at the time had received intelligence information relating to espionage, tax evasion and money laundering.
For the last six months, the collected data was being analysed until a month ago when investigations started officially with the constitution of a team of personnel from CID, Internal Security Organisation (ISO), External Security Organisation (ESO) and Chieftaincy of Military Intelligence (CMI).
The team is under the supervision of deputy inspector general of police (DIGP) Sabiiti Muzeeyi.
