Around 20 armed men stormed the headquarters of a South Korean oil services company in Nigeria's lawless delta and stole more than $300,000, police said on Sunday, in the latest attack on foreign firms. The group arrived by speed boat and forced their way into the compound of Daewoo Nigeria Limited, a unit of South Korea's Daewoo Engineering and Construction Co Ltd, on Saturday before escaping with some 40 million naira ($307,000) into the maze of tidal creeks, a police spokeswoman said. There were no casualties. Police are investigating whether the attack was the work of ethnic Ijaw militants who abducted four foreign oil workers 18 days ago and have crippled a tenth of Nigeria's production in a six-week campaign of violence. "We are still investigating this attack because the circumstances surrounding it are still not clear," Ireju Barasua, spokeswoman for Rivers State police told Reuters. The raid came only five days after nine men were killed during a suspected armed robbery at the delta headquarters of Italian oil company Agip, a unit of ENI.
