Bobasi MP Innocent Obiri was on Sunday evening locked up at Kisii Central Police Station over accusations of inciting violence and destruction of property.
He arrived in Kisii sandwiched between plain-clothes officers in a white car, which ferried him from Nairobi.
The first-time legislator, who was elected on a People's Democratic Party ticket, was arrested on Saturday afternoon outside Hilton Hotel Nairobi after days on the run.
Police have been looking for Mr Obiri since Wednesday for allegedly storming into a quarry owned by a company called County 45.
The MP had gone to protest against blasting at the site, saying it was causing cracks to houses and schools in Masongo, Nyamonema Bobasi, where the quarry is located.
Mr Obiri spent Saturday night at Central Police, Nairobi, before he was transferred to Kisii by road.
He was escorted by 15 officers and was detained in the male cells.
Mr Obiri, who was wearing a green jacket, looked exhausted and only greeted a group of his supporters who milled outside the police station to witness his arrival.
Kisii County Police Commander Abdi Hassan told the Nation the lawmaker will be arraigned at Ogembo and Kisii Law Courts Monday morning.
He will be charged with creating disturbance and malicious damage to property, the police chief said.
A bodyguard attached to the MP has also been arrested and will be in the dock alongside the lawmaker.
The bodyguard was seized on Saturday night by DCI detectives from Kisii after they smoked him out of his hideout in Kitengela, Machakos County.
"He will be charged with the offences of assault, causing bodily harm and malicious damage to property," Mr Hassan told the Nation.
