Ghanaian musician, Charles Nii Armah Mensah, popularly known as Shatta Wale,  has undergone a probe over his Lamborghini linked to a fraudster jailed in the U.S.

Ghana’s anti-graft agency, Economic and Organised Crime Office (Eoco), confirmed that the singer was quizzed and later granted bail after he turned himself in for investigations on Wednesday.

Shatta Wale’s luxury car, “a 2019 Lamborghini Urus, was linked to “a $4m ($3m) crime involving one Nana Kwabena Amuah, a Ghanaian currently serving jail in the USA,” by the Federal Bureau of Investigation and U.S. justice department, Eoco said in a statement on Thursday.

The anti-graft agency said the musician’s Lamborghini was seized earlier in August, “following requests from the FBI and the US Justice Department to track the vehicle and conduct local investigations in respect of uncovering possible co-conspirators in Ghana.”

The anti-graft agency said the singer “does not also possess any documentation in terms of receipt or transfer documents which shows that he owns or purchased the said vehicle except a custom declaration document in his possession bearing the name of Nana Kwabena Amuah who is currently in jail.”

According to EOCO, the musician has been unable to identify the person from whom he purchased the said Lamborghini Urus vehicle except to say that he purchased it from the “Street” and from someone possibly called “ZAK” who might have contacted him on WhatsApp but whose identity he didn’t know and whose contact he had thrown away.
