The Uganda Police Force is once again on the spot over the torture of suspects, days after suspects appearing in court over the murder of former police spokesman Andrew Felix Kaweesi claimed they had been tortured.

Four police officers have been arrested over the torture of Kamwenge mayor who is currently admitted at Nakasero rotting limbs.

Now Kamwenge town council mayor Geoffrey Byamukama claims that police detectives tortured him from the now notorious high security Nalufenya police detention facility in Jinja district.

The politician who was arrested over a month ago as a suspect in the murder of Kaweesi and two others is nursing deep wounds on his knees and ankles, which appear to have been inflicted by a sharp object.

Ugandan rights activists say grisly images of the torture of a detained politician, showing septic wounds on his body, highlight escalating brutality and impunity by the country’s security personnel.

Pictures began circulating online and in local media on Thursday of Geoffrey Byamukama, mayor of a small town in western Uganda, lying on a hospital bed with gaping wounds on his swollen knees and ankles, and bruises elsewhere on his body.

Security services deny accusations of using torture to wring confessions from suspects. President Yoweri Museveni, 72, has often expressed support for his top police boss whom he has praised for helping contain protests against his government.

Police spokesman Asan Kasingye said two security personnel had been arrested in connection with Byamukama’s torture but gave no further details. “We do not condone torture … it is not our method of work,” he told Reuters.

Sarah Birete, program director at the Centre for Constitutional Governance, disagreed. “Torture to get information from suspects is the standard now and we are yet to see more,” told Reuters.

“This is typical in an illegitimate regime where impunity reigns,” she said, adding police have also been accused of kidnappings and robberies.

The images of Byamukama have elicited widespread anger and denunciation from Ugandans on social media. He was arrested on April 5 on suspicion he had participated in the murder of a senior police official, Andrew Felix Kaweesi, on March 17.

A total of 22 suspects have so far been charged in connection with the murder, although Byamukama was not among those charged. Some of them have appeared in court shirt-less, their bodies also showing what appeared to be torture marks.

Some government critics have pointed to rivalry among various top security officials and said the murder was possibly an assassination by Kaweesi’s enemies within the police.

Eric Rugira, a friend of Byamukama who has visited him in the hospital where he is being treated and held, said Byamukama had told him the wounds came from “hours of torture” at the hands of police shortly after his arrest.
