Stephen Chacha the regional DCI boss said the MP was in the hands of his peers from Nairobi and did not disclose where the MP-elect was being held.
Barasa's lawyer Dr Khaminwa told The Standard that he was also "following up with the police" to know where the MP-elect will spend the night.
"They (police) are yet to tell where they have taken him. I will let you know when I hear from them," Khaminwa said on phone.
Surrender order
The Director of Public Prosecutions (DPP) Noordin Haji had earlier ordered Barasa's prosecution as George Kinoti of DCI gave the UDA politician six hours to surrender to police or get fished out.
The MP-elect claimed he was in Nairobi for the three days security agencies were looking for him.
Barasa is accused of shooting Brian Olunga on the forehead at Chebukwabi in Kimilili on Tuesday, August 9. Olunga succumbed to the injury at the Kimilili hospital.
"I'm ready to cooperate with police so that I can also know what killed that young man (Olunga)," he said.
After the questioning, a relative was seen passing warm clothes to Barasa before he was driven away.
The UDA MP-elect recaptured his seat after garnering 26,861 votes against DAP-K's Brian Khaemba's 9,497. The Kimilili Returning Officer George Omondi on Thursday August 12 refused to hand over the election certificate to Barasa's agents.
