A member of Parliament and opposition spokesperson was found dead on Thursday riddled with bullets in Kinshasa, leaving the residents of the Democratic Republic of Congo capital in shock.
The body of Cherubin Okende, a former Transport minister turned opposition politician, was found in his car on one of the city's main roads a day after he was reported missing.
His tragic death occurred as he was due for a meeting at the constitutional court to "study and draft a report on the written declaration relating to your assets after your departure from the government," read a letter from Judge Sylvain Lumu.
The government condemned his murder, terming it an "odious act" and directed "a thorough investigation in order to shed light on this unacceptable act," the spokesman Patrick Muyaya said.
Mr Katumbi, speaking to French radio broadcaster RFI, said Okende's killing was "a political assassination...to reduce us to silence."
President Tshisekedi, in office since 2019, is also due to stand for re-election.
