Alois Mabhunu, a homicide detective, was on duty at the annual Zimbabwe International Trade Fair in the western city of Bulawayo when he had the urge to purge, The Guardian reported.
Unable to hold the call of nature, Mabhunu rushed into a bathroom reserved for President Robert Mugabe.
"Under intense pressure from the call of nature, the officer forced his way in and managed to relieve himself," an unnamed official said. "He was arrested on 7 May after a report was made to Mugabe's security men and to senior police officers in the city."
Mabhunu was being held in police detention in a barracks on the outskirts of Bulawayo. His attorney, a leading Zimbabwean human rights lawyer, is challenging his detention.
"There has to be a law saying the toilet is the president's, but this was a public one," said attorney Beatrice Mtetwa. "They will have had to issue a proclamation in the government gazette specifying it. I bet they didn't do that."
