Ex-Delta State governor, James Ibori, arrived Nigeria Saturday and was immediately picked up by the DSS operatives and moved to their office for what was described as a briefing.
He has however left the Department of State Services (DSS) office in Abuja. He was released after holding a meeting with Lawal Daura, the DSS director-general.
The former governor of Delta state returned to the country on Saturday after serving a jail term for fraud in the UK.
Ibori is eagerly being awaited in Oghara, his home town in Delta state, by his relations and supporters.
