Bobasi MP Innocent Obiri and his aide will be arraigned in Kisii on Monday after their arrest over incitement charges.
Mr Obiri was seized outside Hilton Hotel in Nairobi on Saturday afternoon while his aide was picked from a hideout in Kitengela, Machakos County after days on the run.
The aide spent the night at the Kisii Central Police cells where he had been transferred from Kitengela while Mr Obiri was booked at the Central Police Station in Nairobi, but was expected back in Kisii later on Sunday evening.
Kisii County Police Commander Abdi Hassan said Mr Obiri will face charges of incitement, disturbance and malicious destruction of property when he is brought to court on Monday.
“We have finalised with investigations and he will be in court to answer to those charges,” he told Nation by phone.
The PDP party MP had Wednesday stormed into a private quarry in Masongo, Nyamonema Bobasi and roughed up staff after he went to protest the blasting at the quarry.
Mr Hassan said the aide allegedly assaulted the quarry site manager.
A pickup truck used to ferry workers to and from work was also set ablaze by knife wielding goons who raided the site hours after the MP had left the quarry.
“We have finished with investigations and strongly believe the MP has a case to answer in regards to the incident,” said Mr Hassan.
Security outside the Kisii Police Station remained tight on Sunday following the information that the MP had spent the night at the cells.
