Embakasi East MP Babu Owino has been moved from Wang'uru police station in Kirinyaga to an unknown destination.
In a video seen by the Star on Thursday, three cars were seen leaving the police station.
Earlier in the day, family members and friends of Babu Owino stormed Wang'uru police station, demanding his release.
The MP's team attempted to enter the police station but police ordered them to leave.
Women present were heard wailing as others asked why they were being harassed.
"Why are you harassing me in a police station? We were harassed at night and now we want Babu taken to court if he has broken any law," a woman was heard shouting.
Babu was allegedly arrested on Tuesday upon his return from Mombasa.
He was reportedly arrested by Directorate of Criminal Investigations officers at Jomo Kenyatta International Airport.
The alleged arrest comes amid the anti-government protests called for by the Azimio la Umoja coalition.
