Did they really cut a woman's breast in Calabar because she stole? (graphic photo)

I can't verify the authenticity of this photo. Someone just sent this to me and claims it happened in Calabar. A female petty thief was allegedly attacked by a mob and then they cut off her left breast. If this really happened, then big shame to these people. And look at a fellow woman walking behind her. What a shame! See the full photo after the cut...(warning - graphic content)
