Former Nacada boss John Mututho has accused some police officers of harassing his family members.
Mututho says detectives from two police stations in Nairobi have been arresting some of his children, who he says are innocent, on matters that are basically commercial disputes.
He was speaking to the Star newspaper on Saturday.
He blamed his sons' woes on his stance in the fight against alcohol and drugs.
"My family members just like their father are good people, they have never tasted alcohol or these hard drugs. They are into honest business which now has turned into harassment," said the former Nacada boss.
"Let commercial cases go to the commercial courts.... stop using them to harass my family members and fighting my children's businesses in the guise of shallow law and order illegalities," he added.
He accused some officers of protecting some people from Pakistan who masquerade as car dealers yet they are behind his children's tribulations.
"I am now ready and able to defend my family members...be warned," he said.
" I defeated the drug cartels and brought down their empire during my tenure, they are now on a revenge mission, " he added.
He added that some prominent politicians and public officers are behind the drug trafficking menace and increased alcoholism in the Mount Kenya region which include the dreaded Zombie Drugs and technical Ethanol.
Mututho said he will fight to the tooth against newly created technical ethanol which is responsible for multiple deaths in Mount Kenya and the zombie drug that is prevalent in Nakuru and the coast, especially Malindi.
"The import of these drugs is by prominent people," he said.
"The officers who are protecting people from suspicious Pakistan Nationals in international and local Illicit Drugs circuits are well known by Authorities and masquerade as car dealers."
