Femi Falana said Sisiku Ayuk Tabe, the President of the anglophone separatist movement in Cameroon, and nine others, were detained at a hotel in Abuja last weekend.
"Armed operatives of the State Security Service (Nigeria's secret service) invaded the venue, abducted our clients and took them away to an undisclosed place," he said. The intelligence agency has denied any arrests but rumours have swirled about the men's possible whereabouts.
Nigeria's Foreign Minister, Geoffrey Onyeama, on Wednesday told reporters he had met the security agencies and said questions remained about the identity of those detained. "I don't know whether to call it an arrest or it could be people just called in for questioning or whatever. The investigations are on-going," he said after a cabinet meeting.
Falana, however, called for his clients to be either released from "illegal custody" or charged within 48 hours, threatening court action "to secure the enforcement of their fundamental rights to personal liberty".
The leaders have not been in contact with their families or legal team, he said, adding he had "confirmed" the government in Yaounde had asked Abuja to repatriate the men.
"Our clients are not illegal immigrants in Nigeria as some of them have been granted political asylum by the federal government while others have valid permanent resident status in Nigeria," said Falana.
