Detectives from the Directorate of Criminal Investigations (DCI) on Thursday nabbed 34 illegal immigrants for allegedly peddling drugs in Kasarani.
They included 33 Nigerians and 1 Eritrean who were posing as students from the nearby United States International University (USIU) and Kenyatta University (KU).
Kasarani OCPD Peter Kimani said the suspects have been operating businesses around the institutions of higher learning with the intention of selling drugs.
Also arrested during the raid was the owner of a popular club behind the Thika Road Mall (TRM), who is accused of aiding the immigrants.
Police further indicated that the suspects had been terrorising residents as they were linked to a spate of robberies in the area.
The raid follows a recent security shake-up at Kasarani police station with the former leadership accused of being in bed with the suspects.
The suspects are expected before the Kiambu Law Courts.
In August 2018, 19 Nigerians were arrested in Umoja, Kasarani and Roysambu estates in Nairobi for conning Kenyans through scams on Facebook and other social media sites.
Two of the suspects were accused of running a pseudo account for the First Lady Margaret Kenyatta and using it to scam unsuspecting internet users.
