The Independent National Electoral Commission said it is investigating a slew of complaints about the election in Rivers state, including that officials from Jonathan's government and party substituted polling officials and that official results sheets went missing. The alleged rigging affected five southern states and apparently occurred between the count at polling stations, which their agents monitored, and collation at ward and then local government levels before results were sent for the final tally in Abuja, the capital, Lazarus Apir, the monitoring group's program manager, told The Associated Press.
