On February 19, police arrested 46 people on charges of treason, in Harare, as they watched videos of protests in Egypt and Tunisia and discussed possible demonstrations in Zimbabwe, where Mugabe has been in power for 31 years.
Earlier in March, a Facebook group tried to organise a mass demonstration that was largely unsuccessful.
Not only has the security regime targeted Facebook activists, several leading opposition figures and MPs including Elton Mangoma, the energy and power development minister, have been arrested.
