Gatundu south MP Moses Kuria, Kabete MP Ferdinand Waititu, Machakos Senator Johnstone Muthama and Suna East MP Junet Mohamed spent the night in police cells.
The four are facing charges of spreading hate speech in separate gatherings on Sunday and Monday.
Kuria was caught on camera Sunday telling a gathering in Kasarani stadium that the opposition leader Raila Odinga should be assassinated.
Mohamed spewed hate while responding to Kuria’s remarks at an ODM press briefing on Monday.
Others who are facing similar charges are Bahati MP Kimani Ngunjiri, Kitutu Masaba MP Timothy Bosire, Busia woman representative Florence Mutua and Kilifi woman representative Aisha Jumwa.
The eight were arraigned in court Tuesday but did not take pleas because the charge sheets were not ready, The Star reports.
They were detained for four days, Citizen Digital adds.
