Fake new currency in Kenya
Earlier in the week, three people were arrested in Yatta, Machakos County with fake notes of the new Kenyan currency.
The three - a Congolese, a Nigerian and a Kenyan - were ambushed in Kakumuni village after residents raised suspicions over their activities.
"We believe they chose such a place because of less suspicion but we will get them," Machakos County Commissioner Farah Maalim conveyed.
