A lot of shops in the Ikeja area of Lagos were locked and many streets deserted as people in white were seen walking around the area. The reader who witnessed it yesterday and sent in the photos said it’s the ‘Oro’ (a traditional rite) activity.

That is not correct because I could see picture of a woman amongst the people wearing wearing white uniform. Traditionally, women are not allowed to paticipate in oro festival. If a woman sees oro, she will die that day.
