Mawarire was treated fairly by Zimbabwe police

Evan Mawarire, the Zimbabwean pastor whose #ThisFlag social media campaign contributed massively to a significant stayaway two weeks ago, says he is now "seriously" worried about returning home after hearing President Robert Mugabe denouncing him.

Mawarire said he and many others in Zimbabwe feared arrest although the police had treated him fairly at Harare Central Police Station.

"The police were cordial. But the cell was terrible. There were 22 of us in the cell no bigger then 10m x 10m and the blankets had been defecated on. We had to use the blankets as it was cold, and the smell, Oh!"

He said when he was taken the next day to the shabby Harare Magistrate's Court. a sewer pipe along the walkway next to the cells was burst. "I had to eat my lunch next to that," he said.

On his Facebook page, Mawarire had said he was going home. But that was before hearing what Mugabe said about him. Now he says is a very worried man and uncertain about the future.
