The Department of State Services (DSS) has arrested a former Chief of Army Staff (COAS) Lieutenant General Azubuike Ihejirika (rtd).
Ihejirika was arrested on Tuesday night at his Maitama, Abuja residence.
It was gathered that the former COAS is being investigated over his alleged sponsorship of the Independent People of Biafra (IPOB) agitators.
It was also learnt that his arrest was not unconnected to the ongoing $2.1 billion arms purchase probe involving former National Security Adviser, Colonel Sambo Dasuki (rtd).
Since his retirement, various allegations have been levied against the former COAS including that raised by an Australian, Stephen Davis who was invited by the Federal Government to negotiate with extremist sect, Boko Haram.
Davis in his report, alleged that Ihejirika and a former Borno State Governor, Ali Modu Sheriff were among the financiers of the terrorists sect.
But the duo have since denied the allegations, with Ihejirika describing it as frivolous and a ploy to distract security agencies.
