Dodoma: Daniel John has been found murdered after he was kidnapped on Monday.
John, the top official of the Chadema opposition party, was found beaten to death, with machete wounds to the head.
“Daniel John was kidnapped on Monday in the street by men in a car,” party chairperson Freeman Mbowe is quoted saying.
“They were beaten and tortured, and the torturers were asking why they were campaigning for Chadema’s candidate.
John was responsible for the Chadema party in the Hananasif district of the economic capital Dar es Salaam, where a heated local election campaign is under way.
Mbowe accused supporters of the ruling Chama Cha Mapinduzi (CCM) party of being behind the attack.
In September 2017, senior opposition lawmaker Tundu Lissu was shot several times at his home in the capital Dodoma.
He was rushed to the Kenyan capital Nairobi where he was in intensive care for several months before being transferred to a hospital in Brussels.
Tanzanian President John Pombe Magufuli has been increasingly criticised over his authoritarian leadership style, with a clampdown on the opposition, journalists and artists.
