According to Amnesty International, eleven people are believed to have been killed and 30,000 people left displaced over the past year after the forced evictions in waterfront communities in Lagos State.
The rights groups states that townspeople left gunfire and burning homes, while others are believed to have inundated in the chaos.
It stated that state security forces assaulted residents who opposed to move. Residents claimed the evictions were executed in violation of court orders.
This happened a year after the residents of the Otodo-Gbame community were displaced from the shores of the commercial capital, Lagos.
In reaction to the report, a representative for the Lagos State Government said to BBC that the accusations are incorrect and overstated.
He stated that the violence happened because of the inter-ethnic fights and not because of the government-led demolition.
Nigeria is one of the party to international and regional human rights treaties that prohibit it from executing forced evictions.
The former residents of the communities are organizing a rally tomorrow to mark the anniversary of their eviction.
