The arrest came just hours after President Kenyatta sacked Gen Ogallo and replaced him with Brigadier (rtd) John Warioba.

Officers from the Kenya Anti-Terrorism Police Unit (ATPU) yesterday arrested outgoing prisons boss Wycliffe Ogallo, Kamiti Maximum Prison head Charles Mutembei and his deputy.

The arrests came just hours after President Kenyatta sacked Gen Ogallo and replaced him with Brigadier (rtd) John Warioba, and just two days after the Kamiti jailbreak that saw three terror convicts escape.

Queries have arisen over how they managed to escape from the country’s most secure prison on Monday.

Gen Ogallo, Mr Mutembei and his deputy were taken to DCI offices after the arrest.

The new prisons boss, Brig Warioba, declined to comment on the arrests, saying it was too early as he has just been appointed.

Hours after the arrest, the National Police Service tweeted that Gen Ogallo was not arrested, but only escorted home from his office.

However, his dramatic seizure at Magereza House, along with that of Mr Mutembei and his deputy, was witnessed by journalists and captured on film.

When he attempted to sit at the front of the vehicle, the officers blocked him from doing so and sandwiched him in the back seat before speeding off.

NPS did not clarify why Gen Ogallo was escorted by a heavy security team comprising ATPU officers.
