On Thursday, Eons Intelligence reported that his demise followed an attack by the Islamic State West Africa Province (ISWAP), a splinter group.
ISWAP fighters, led by its commander, Bana Duguri, stormed the Sambisa hideout of Boko Haram.
Shekau was said to have blown himself to avoid being captured alive.
This is not the first news about the death of Shekau. If true, ISWAP will likely make an announcement in the coming days.
A source revealed that the Nigerian military and intelligence agencies are in touch with the development.
