On 11 April 2011, the pressure group Activists for Change (A4C) held its first Walk to Work protest near Kampala, in response to a comment by President Museveni on the increased cost of fuel, which had risen by 50 percent between January and April 2011. He said: "What I call on the public to do is to use fuel sparingly. Don't drive to bars." The protest, which called on workers to walk to work to highlight the increased cost of transport in Uganda, was disrupted by police, who fired tear gas and arrested three-time presidential candidate Kizza Besigye and Democratic Party leader Norbert Mao. In the course of the protest, Besigye was shot in the right arm by a rubber bullet. The government blamed the violence on protesters.
