Gunmen abducted another foreign worker in the oil-rich but restive Niger Delta region on Wednesday, an oil industry spokesman said.
"The man is an employee of Homan Engineering. He was abducted from his car in Bayelsa State and taken to an unknown location," the spokesman for a major oil group told.
He did not disclose the identity or nationality of the seized man in the latest abduction to hit Africa's biggest crude producer in recent weeks.
Homan is an oilfield and steel construction services firm based in the oil city of Port Harcourt, the scene of a spate of kidnappings in recent weeks, the spokesman said.
Police confirmed the incident, but said it occurred on the border between Bayelsa and Rivers states.
"The incident occurred on Wednesday morning at a junction close to Bayelsa state. But the place is in Rivers," Bayelsa police commissioner Hafiz Ringim said.
The past weeks have seen some 15 foreign oil workers taken prisoner in the west African country, but nine of them were released this week.
