He was sentenced by the Federal High Court in Abuja on Wednesday, alongside Obi Nwabueze, his co-accused.
His elder brother Henry Okah had been sentenced for a similar crime in South Africa, where he was based.
Recall that a dozen people were killed in the bombing at the Eagle Square, Abuja during the Goodluck Jonathan administration.
The presiding judge, Justice Gabriel Kolawole, in a 4 hour, 30 minutes judgement found the defendants guilty as charged for being responsible for March 15, 2010, bomb blast which claimed one life in Warri, Delta State and the October 1st, 2010 bomb blast near Eagle Square in Abuja which claimed several lives.
The ruling was in accordance with section 15 sub sections 1 and 2 of the EFCC act.
The judge noted that the second defendant, Obi Nwabueze, particularly made himself available to run illegal errands for Henry Okah by providing N1.2m used to purchase five fairly used cars deployed for the Warri blast, while Charles Okah, provided the sum of N2m used for the purchase of the four cars deployed for the Independence Day blast in Abuja.
