Men of the Nigeria Police Force conducted a raid on the Abuja residence of South-South leader, Edwin Clark.
According to the Ijaw statesman, they came without prior notice but were not refrained from doing their job after showing a search warrant.
Clark said they found nothing incriminating in his house.
"There was no notice before the search. The policemen just walked in and demanded to search the house," he said.
"When they came, my secretary wasn't around and they did not have access to the office because it was locked but they insisted that the office must be opened. They eventually searched the place but didn't find anything incriminating.
Meanwhile, the Police IG, Ibrahim Idris in a swift reaction, has ordered the detention of the policemen who conducted the raid.
Clark, 92, said he is being suspected of harbouring weapons in his residence.
