Numbi, who holds the rank of general, is one of eight senior police officers named as "national heroes" by President Joseph Kabila
Numbi, who holds the rank of general, is one of eight senior police officers named as "national heroes" by President Joseph Kabila in a May 16 ruling seen online on Tuesday.
He was relieved of his post after the 2010 killing of Floribert Chebeya, founder of the rights movement Voice of the Voiceless, who was found dead in his car on June 2, a day after he was driven to police headquarters in Kinshasa following a summons from the police chief.
Chebeya's driver, Fidele Bazana, went missing without a trace, and in the absence of a body the judiciary concluded that he had also been murdered.
Numbi denies having any appointment with Chebeya on that day and has only once appeared in court, as a witness.
In 2011, a military court sentenced a senior police officer to death and jailed a police captain for life over the murder, but four years later, the death sentence was commuted to 15 years jail and the captain acquitted after an appeal.
"It's authentic, it's an official decree," a staff member working at the official government gazette told AFP in reference to the document posted online.
"It is a huge disappointment. This decision proves that the assassination of Floribert Chebeya and Fidele Bazana really was a crime perpetrated by the state," Rostin Manketa, executive director of Voice of the Voiceless, told AFP.
Kabila "knows that John Numbi's name has been cited in this affair from the beginning... we never would've expected this," he added.
Over the years, Chebeya became highly critical of the regime of Kabila, who was propelled into office in 2001 by Kinshasa politicians after his father Laurent-Desire Kabila was assassinated while the country was at war.
In September 2016, Washington placed Numbi on a blacklist of undesirable persons, describing him as "an influential advisor to President Kabila".
During a ceremony in Paris on June 2 to mark the seventh anniversary of Chebeya's murder and Bazana's suspected murder, their families said they remained hopeful that the truth would emerge.
