Obado denied ownership of three guns found at his Lavington home.
He was told to record statements with officers from the DCI Serious Crime Unit.
Sources said Obado told police he was a licensed gun owner, but only owned one firearm.
He told investigators the two other pistols recovered from his Nairobi home belonged to his bodyguards.
He said he has five bodyguards who are APs who use his safes in his Nairobi and Migori homes to keep their guns.
All government firearms are clearly labelled. The guns that have landed Obado in fresh trouble are two Ceskas recovered from his Lavington home.
Obado was nabbed at the hotel’s basement where he took cover after he was told of police presence outside the hotel. A taxi, which police said Obado wanted to use to escape, was at the basement when police arrested the governor.
Detectives from the Special Crime Prevention Unit whisked Obado to the old Nairobi area offices before he was transferred to the DCI headquarters in Kiambu.
