The Nigerian police reported Sunday, that a Dutch man was shot and killed in front of his house in Port Harcourt in spite of the dusk to dawn curfew and daily military patrol in the state capital. But, the Nigerian police described the murder as a revenge attack, because, the killers left a note on his corpse. The note said they had given him 50,000 dollars (35,000 euros) to import cars from Europe but that he had neither returned the money nor supplied the cars. Felix Ogbaudu, police chief of the southern oil-rich Rivers state told the AFP news agency.

In another tragic incident last Thursday, armed robbers in a high-speed boat killed three passengers on another boat in the Bonny lagoon in Rivers state after robbing them of their money and other valuable possessions. Eyewitnesses said that, one of unfortunate passengers recognized a member of the gang of armed robbers and they killed him and two other passengers to prevent them from disclosing their identities to the police.

Rampaging cultists and militants have besieged Rivers state since July and over 200 people have been killed in violent confrontations between rival gangsters and attacks on oil companies.. A special military task force of the Nigerian Armed Forces had to take over the law enforcement operations when the Nigerian police failed to secure lives and property in the oil city of Port Harcourt.

Recurrent violent attacks and kidnappings of foreign oil workers and some local targets have jeopardized the safety and security of both the multinational oil companies and their host communities since the ruling People’s Democratic Party (PDP) employed armed gangs to rig elections and overpower the opposing parties. The well armed militants and bandits have forced Shell, Chevron, and other oil majors to shut down during emergencies and reduced oil export by a quarter.
