Police on Saturday night arrested ten Ethiopian immigrants at a farm in Ruiru following a tip-off from the public.

The foreigners were arrested in Gikumari village as they were being dropped in a Probox, ready to board an awaiting lorry.

Ruiru Deputy OCPD Mr Birgen Kiptoo said they conducted the swoop after a tip-off from the public on the presence of strangers and suspicious people at the farm.

"We are yet to know where they were going but the aliens are held at Ruiru Police Station as investigations continue," said Kiptoo.

The foreigners were all men, with Ethiopian passports. Three Kenyans, the lorry and Probox drivers and a turn boy, were also arrested.
