The latest government action came a day after dozens of students in the capital Managua were besieged by pro-government forces for hours in a parish church next to the National Autonomous University of Managua (UNAN) before finally being allowed to leave after the intervention of Catholic Bishops.
Paramilitaries attacked the car of Abelardo Mata, the Roman Catholic bishop of Esteli, breaking windscreens and windows and damaging the tyres.
Protesters have been demanding the resignation of President Daniel Ortega.
More than 300 people have died during months of anti-government protests.
Following the latest clashes, a group of about 150 students were holed up in a church building close to the main university in the capital, Managua, along with priests and journalists.
