Self-proclaimed National Resistant Movement general Miguna Miguna might have spent the weekend at a police station in Lari, Kiambu County, after police refused to free him on Friday despite a court order.
Sources indicate that Mr Miguna, who was picked at his Runda home on Friday morning, was taken to Githunguri Police Station then transferred to Uplands Police Station.
Police have, however, denied that the lawyer was being held at the station, even though they kept it tightly guarded from Saturday.
On Sunday, his lawyer Edwin Sifuna, Suna East MP Junet Mohamed and Busia Woman Representative Florence Mutua visited the station but the officer in charge insisted that Mr Miguna was not there.
However, Mr Sifuna insisted they had reliable information that the lawyer was detained at the Uplands station.
