Abuja, Nigeria ? Militants disguised as soldiers took a German oil industry worker hostage Thursday in Nigeria’s oil-rich delta region, spiriting him away on a boat, police said.

Ten attackers in camouflage uniforms abducted the man after stopping his jeep as he traveled to work in the oil-producing hub of Port Harcourt, police spokeswoman Ireju Barasua said.

The man works for construction company Bilfinger Berger Gas and Oil Services Ltd., an affiliate of German construction giant Julius Berger, Barasua said. Company officials could not be reached for comment.
