Angry youth have attacked and injured 14 Chinese nationals at the Duka Moja railway construction site on the Narok-Maai Mahiu road in Narok County.
The victims have sought treatment at the Narok Referral Hospital following the Tuesday afternoon attack.
A journalist who was covering the event for a local television station was also attacked.
The more than 200 club- and sword-wielding youth descended on the workers, chanting and shouting.
Local youth have been demanding a share of the standard gauge railway construction jobs in the area.
Recently, more than 300 youth protested against a Chinese contractor at the Duka Moja trading centre demanding jobs but police dispersed them after they attempted to block the road.
