Nigerian sources say they are expecting President Muhammadu Buhari to return home after an extended visit in London that has caused much public speculation about his health.

Activity at the president’s Aso Rock villa suggested that his return is imminent, as aides prepared for Buhari to arrive as early as Saturday, the Nigerian Tribune reports.

The 74-year-old Buhari left on January 19 for a vacation in the United Kingdom, and was expected to return after a 10-day stay. He subsequently notified Nigeria’s National Assembly in writing that his return was delayed as he waited for medical tests to be completed.

Questions about Buhari’s health touched off a storm of unsubstantiated rumors, including those of his death. That’s led The Association of Nigerian Entrepreneurs in the Diaspora group to demand that the federal government arrest anyone spreading rumors about Buhari’s health.

“The mongers have brought emotional pain and torture not only to the members of the president’s immediate family, but to his friends, associates and indeed many Nigerians who had been distressed by the evil rumor,” said group chairman Charles Sylvester in a statement Friday.

Clamor over Buhari’s whereabouts led the president to release photos to verify his well-being, including social media posts about official meetings. The Senate President also confirmed that he’s spoken with Buhari this week.

Nigerians at 350 different mosques said prayers for Buhari on Friday, at the request of a government official.
