The Department of State Services (DSS) has released labour leader Joe Ajaero.
It was gathered that Ajaero was allowed to go home around 11 pm on Monday.
The Nigeria Labour Congress president told Channels TV that he was grilled for about 15 hours since his arrest around 7 am at the Nnamdi Azikiwe International Airport, Abuja.
Ajaero, however, said his travel passport was seized by the secret police.
The labour leader said though he was detained by the DSS, some police officers also came around to grill him at the DSS office in Abuja over the #EndBadGovernance nationwide protests that took place in August.
Ajaero said he was quizzed over alleged terrorism financing involving a British national, Andrew Wynne.
Recall, the labour leader was on his way to the United Kingdom on Monday for a Trade Union Congress (TUC) event when he was arrested at Abuja airport.
Further recall, the Nigeria Labour Congress had given Monday midnight as ultimatum to the Federal Government to unconditionally release its President, Joe Ajaero, or face dire consequences.
