At some point, former Attorney-General Amos Wako and Director of Public Prosecutions Keriako Tobiko were taken to task by a Kenyan court to explain why it was unable to trace whoever was running Mr Kabuga's business empire.
In its response to court, the Daniel arap Moi administration claimed that Kenya Trust Company (KTC) Ltd, which was collecting hundreds of thousands of shillings every month from apartments owned by Mr Kabuga and his wife, had no known address.
Mr Kabuga was able to register a business in Kenya and co-owned House No. 6 on LR No. 1/1154, also known as Spanish Villas, on Lenana Road in Nairobi with his wife, Josephine Mukazitoni.
Following international pressure, Mr Wako in 2008 went to court seeking orders barring the Kabugas from Spanish Villas until the conclusion of a case at the International Criminal Tribunal for Rwanda (ICTR), where Mr Kabuga was on trial.
Although the physical address of KTC Ltd is not known, the company had been collecting rent and depositing it in an account that was owned by Mr Kabuga at the Commercial Bank of Africa.
