The ongoing trial in the murder of Kampala businessman Henry Katanga on Wednesday , took a dramatic twist after discrepancies in call data records raised questions about the credibility of the testimony of a key prosecution witness.

Timothy Nyangweso, a presenter at state broadcaster Uganda Broadcasting Corporation (UBC) and a church minister at Watoto Church took to the witness stand but the defence lawyers were quick to poke his credibility pointing out that he lied severally when he recorded a statement saying he called one of the daughters of the late Katanga on the fateful day.

The development sparked intense debate in the courtroom, with the defense team seizing on the inconsistencies to challenge the prosecution's version of events.

Evidence presented by the defense contradicted the testimony of witness Timothy Nyangweso, cousin of the late Henry Katanga.

Nyangweso had earlier testified that he called Martha, Katanga's daughter, on November 2, claiming she told him about Katanga's death.

However, during cross-examination, defense counsel Elison Karuhanga presented a call data list that showed no record of Nyangweso's number.

" I called her around 8:30 am. I called her twice, and on the third time, she picked up," Nyangweso said in response to questions by the lawyer.

The defense counsel further questioned Nyangweso about his statement, pointing out that it did not include his telephone number.

The exchange highlighted the inconsistencies in Nyangweso's testimony and raised doubts about the reliability of his evidence.

The defense has maintained that the prosecution's case is based on unreliable witness statements, and the call data evidence has further weakened their argument.

The trial has been adjourned until Friday July 12.
