At least a dozen people, including the jailer and deputy jailer, were on Wednesday injured at a jail in Meerut in a clash between prisoners and officials.
Police had to resort to firing to bring the situation under control. Along with police officials, personnel of the Provincial Armed Constabulary and Rapid Action Force were also present on the spot.
"The clash began after some prisoners started beating the jail officials. The rioting prisoners also set ablaze the common mess using gas cylinders from the kitchen. We are trying to bring the situation under control," District Magistrate Vikas Gotalwal said, adding that a judicial inquiry will be carried out.
"Those injured have been taken to the hospital," he said.
According to sources, the prisoners were angry at the jail officials as the latter had beaten up one of them two days ago.
On Tuesday, some visiting police officials had beaten up some prisoners, sources said.
