A Nairobi court has dismissed terrorism charges against Worqu Dejene Sar and his father Sar Guracha Haro.
The two had been charged with six terrorism related acts, over twin explosions which occurred in two buses in Githurai in 2014.
Chief magistrate Francis Andayi said the police failed to link the two against the alleged terrorist acts.
The court, however, found Mr Haro guilty of threatening a witness for testifying against his son.
The twin blasts killed three people and injured 67 others.
