A Ugandan software developer, Peter Ivan Egessa, went missing in the neighbouring Rwandan capital Kigali, in December 2019.
Relatives and employers say they have failed to locate Egessa, 32, who went missing at the beginning of December 2019.
Despite media reports, the Ugandan Ministry of Foreign Affairs has maintained a deathly silence on the matter.
The spokesperson of the Ministry of Foreign Affairs, Moses Kasujja, told Daily Monitor they would issue a statement.
Annet Kikomeko, the sister of Egessa, told Monitor the family reported his disappearance on January 2.
She visited the Interpol offices in Kampala and they promised to send a letter to their counterpart in Rwanda.
Even during a joint press conference by Foreign Affairs minister Sam Kutesa handed over nine Rwandans to the Rwanda High Commissioner, Maj Gen Frank Mugambage, on release of Rwandans, Egessa was never mentioned.
Emmanuel Musengeri, the brother to Egessa, said after Egessa disappeared, his employers were called by someone with a concealed number asking them to obtain details about him.
He suspects his brother is being held by Rwandan security operatives.
His employer’s investigations discovered that the phone call was from Rwanda Immigration Department which still denied knowledge of the matter.
