Police said Sunday they are holding 24 illegal immigrants who were arrested on Saturday during a sting security operation in Isiolo.
George Kinoti, director of Directorate of Criminal Investigations (DCI), said 18 Ethiopians and six Eritreans were arrested from a bush in an operation by a team of detectives in Merti.
"The immigrants were found being driven through the bush from Moyale to Nairobi to avoid detection. Driver escaped but is being sought," said Kinoti.
He said the suspects will be arraigned in court on Tuesday, charged with being in the country illegally.
Kenyan authorities have intensified a crackdown on undocumented migrant workers.
The immigration department has set up a hotline for citizens to report.
