Top sources within the DSS said Kuku, who had been in the United States since 2015, was being aided by the Federal Government agency to escape justice.
According to DSS, the agency aiding Kuku claims to be probing him but is doing the opposite.
Although the DSS did not name the agency, it had been reported that the Economic and Financial Crimes Commission had been probing the former presidential aide for sometime.
DSS said, “It is sad to note that, in the course of our investigation, we discovered that an agency, which is also saddled with an investigative authority, is rather creating a platform for criminal fugitives.
“We discovered, in particular, a fugitive, who is widely known to have looted our commonwealth, still has the audacity to use the machinery of that particular agency to harass and haunt adversaries who are aware of his loot and heinous crimes.
“From our findings, we discovered that the agency in reference is now in criminal connivance with fugitive Kingsley Kuku, a former Special Adviser to President Goodluck Jonathan on the Federal Government Amnesty Programme on the Niger Delta.
“Sadly enough, the agency in question, which claims to be investigating the fraud, is ironically directly and brazenly facilitating the concealment of the looted several billions of naira belonging to the Niger Delta Amnesty Programme.”
DSS said the government agency, which recently raided the home of a former Deputy Speaker of the House of Reps, Chibudom Nwuche, carried out the raid based on the instruction of Kuku.
