An unexploded suicide vest has been found in Kampala after Sunday's deadly attack on people watching the World Cup final on TV, Ugandan officials say.
They also say that an unspecified number of people have been arrested.
At least 74 people were killed in the twin explosions at a rugby club and a restaurant.
The Somali Islamist group al-Shabab has said it was behind the attack because Uganda is supporting Somalia's government in Mogadishu.
Government spokesman Fred Opolot said the arrests were made after the vest was found in the Makindye area south-east of Kampala.
The vest was found in a black bag similar to those used for carrying lap-tops in a nightclub on Monday afternoon, police say.
It apparently contained ball-bearings, explosives and a detonator.
The nationalities of those arrested has not been released but officials have said a head found near the site of one of the blasts appeared to belong to a Somali national, who may have been a suicide bomber.
The Ugandan police are being helped by American investigators as they try to work out exactly how the explosions were planned and detonated.
BBC East Africa correspondent Will Ross says the Ugandan authorities are under great pressure to show that they can prevent any repeat of Sunday's devastating blasts.
The African Union, which has sent peacekeepers to Somalia, is holding a summit in Kampala later this month and officials say it will go ahead as planned.
