Police are investigating allegations of fraud in cellphone-based mobile money transfer operations countrywide. Telecommunications' company, MTN, is reported to have lost billions of shillings in the rip-off which took place last year. At least one more communications company, according to sources, is also said to have been a victim of another scam. With investigations underway, loopholes which had made it possible for the various swindles to take place are reported to have been plugged, preventing any further losses. Customers' money has, however, not been affected in the fraud which was reportedly made possible through the collusion of employees of the affected companies. One MTN official in the Public Access Department has been interrogated by detectives over the fraud, sources said yesterday. MTN Corporate Affairs Manager Justina Ntabgoba-Kayemba, in an email sent to Daily Monitor yesterday, confirmed that an investigation into the matter is ongoing.
