Four Turkish citizens have been freed a week after they were kidnapped at gunpoint in Kwara State, the police said.
Police said they had “successfully secured the release” of the men on Friday and that no ransom was paid to the kidnappers.
Spokesman Frank Mba told AFP on Sunday that the four were in “good health”.
“We have three suspects in custody and recovered one AK-47 rifle. We are now intensifying our search for others involved,” Mba said.
The gunmen snatched the four men after storming a bar in a village in the western Kwara state last Saturday.
Local media said the Turks were working for a construction firm in the state.
