Former Deputy Executive Director of the National Service Authority, Ms Gifty Oware-Mensah is set to present herself to the National Investigation Bureau (NIB) when she returns to the country Tuesday afternoon.

However, Myjoyonline.com sources at the NIB suggest she will be arrested upon her arrival at the Kotoka International Airport, from where she would be taken into custody for interrogation.

Key players in the New Patriotic Party under which regime she was appointed Deputy Executive Director reported to be mobilising to storm the Airport in order to accompany her to the offices of the NIB.

The NIB is probing her work at the NSS over allegations that thousands of ghost names were used to defraud the state of millions of cedis in allowances.

As the Deputy Executive Director, Gifty Oware-Mensah had responsibility for administration and finance of the NSS and is expected to be a key witness in the ongoing investigations.

The alleged payroll fraud is reported to have cost the state a staggering GHȼ50 million each month.

It is unclear how long the alleged scheme run.

Over the weekend, the government announced an extradition process to bring key suspects in alleged malfeasance back to Ghana, following reports that some individuals wanted to assist in investigations had fled the country to evade justice.

The NIB recently detained and questioned Kwaku Ohene Djan, also a former Deputy Executive Director of the National Service Authority, over the raging allegations.
