KAMPALA, Sept. 4 -- Ugandan police on Monday said that they have arrested three suspects in connection with last week's murder of a Chinese woman in the central district of Mukono.

Polly Namaye, the deputy police spokesperson, told Xinhua in an interview that the three suspects are being held over the Friday shooting of the 60-year-old Yang Yeshu, a branch cashier at Nile Steel and Plastics Company Limited in Mukono.

"We have taken witness statements, got exhibits and extracted the video footage from the security cameras to help in the prosecution," she said.

Namaye declined to name the suspects for fear of jeopardizing the on-going investigations.

The footage from the security cameras shows two men armed with a pistol entering the factory premises, located along the Kampala-Jinja highway, using a motorcycle.

The duo briefly talked with the victim before pulling out a pistol and shot her dead.

"From the footage she died while trying to fight for her life. We shall ensure those who carried out this brutal murder are brought to book," said Namaye.

Yang became the third Chinese woman to have been killed in the east African country in less than a year.

The two other Chinese women were stabbed to death in Kikoni in February, a suburb in the capital Kampala.
