The man in charge of Kenya’s computerised voting system has been found dead just days before the 8 August elections.
Chris Msando, an electoral commission IT manager, had gone missing on Friday.
“There was no doubt he was tortured and murdered,” said IEBC chairperson Wafula Chebukati.
Tension is high as the presidential election is expected to be a close race between incumbent Uhuru Kenyatta and long-time opponent Raila Odinga.
Police said on Monday that the bodies of Mr Msando and an unidentified woman had been found in the Kikuyu area on the outskirts of Nairobi and taken to the city mortuary.
“The only question in our mind is who [killed him] and why he was killed a few days to elections,” the AFP news agency quotes Mr Chebukati as saying.
Kenyan newspaper The Star reports that Mr Msando’s body was found with one arm missing.
