YENAGOA, Rabi'I 19, 1433, Feb 11, 2012, SPA - Nigerians voted amid tight security in a governorship election on Saturday in the state of Bayelsa. Nigeria's 36 state governors are some of the most powerful politicians in Africa's most populous nation, according to a report of Reuters. "Ten thousand to 15,000 policemen are deployed for the election, these include anti-bomb squads from Delta, Edo and Rivers states to ensure that all key points are saved ," said Chris Olakpe, Bayelsa's police commissioner. "We are going to effectively police all polling booths and normal patrols would go on to ensure miscreants do not hijack the process," added Olakpe, who took up his position this week. Bayelsa has a population of around 1.5 million, the least populous state in a country of more than 160 million but it is key to Nigeria's economy due to its substantial oil wealth. --SPA 15:17 LOCAL TIME 12:17 GMT www.spa.gov.sa/969060
