15 bodies in Nigerian river so far

 
Police in Nigeria have found at least 15 unidentified corpses floating on a river in southeast Anambra state, with local media claiming the number could be much higher.
Some local media reports put the number of corpses at between 30 and 40.
It is unclear how the people had died or how their bodies ended up in the river.
Television showed footage of what appeared to be male corpses in the Ezu river in Amansea, a border community between Anambra and neighbouring Enugu state, but a local police official says there have been no recent reports of communal clashes in the area.
