A Mali national was on Monday arrested in Nairobi with Sh1 billion fake notes in dollar and Euro currencies.
The suspect was nabbed in a raid by homicide detectives at a house on Brookside Drive, Westlands.
Detectives said the fake money was in heaps of the said currencies.
They added that the arrest was part of an ongoing operation to weed out illegal immigrants.
An officer leading the investigation said they acted on a tip-off by members of the public.
He said they believe the suspect in their custody is the money launders’ kingpin.
Kenyan victims of the con game were advised to report to the nearest DCI to launch their complaints.
