Kidnapping for ransom has been a long-standing problem in southern Nigeria, particularly in the oil-producing delta region, where criminal gangs target wealthy Nigerians and expatriate workers.
Most are usually released after the payment of a ransom.
A New Zealander and at least two Australians have been kidnapped in southern Nigeria by gunmen who killed their local driver.
In the 2000s, the Movement for the Emancipation of the Niger Delta (Mend) took foreign employees of oil companies in the Niger Delta hostage in exchange for ransom. More than 200 foreigners have been kidnapped since 2006, according to the Nation.
The Nation reports that kidnapping for ransom has since grown to a "frightening level" in Nigeria with ordinary people potential victims and perpetrators.
