The MDC-T held the roadshows at a last minute at Nyika growth point, Makuvaza, Matsvange and Mutikizizi townships.
MDC-T provincial chairman Wilstuff Sitemere said: "The police had called off the roadshow, but we went ahead. We were just moving about and not addressing anyone. We are suprised they wanted us to seek clearence first when Zanu (PF) is just holding rallies and meetings, doing whatever it wants."
"Two detectives approached us but we did not want them to disrupt our programme, so we sped off. I am told they want me for a questioning but I am yet to go to the police," Sitemere said.
He said the police targetted him as the provincial chair for Zaka North. They were also looking for Zaka North Member of Parliament Ernest Mudavanhu and Bikita West legislator, Heya Shoko.
Asked to comment, provincial police spokesperson Inspector Tinaye Matake said: "We just want them for questioning. The roadshows were turned down. It is not like we want to arrest them. Talk to my seniors for more details."
Shoko and Mudavanhu could not be reached for a comment as their mobile phones were switched off.
