More than 60,000 teachers have been appointed since the scheme was introduced in 2000 during Farooq Abdullah’s regime. The issue of holding screening test cropped up in April when a teaching assistant was unable to write a composition on cow during hearing of his case in the HC. On Wednesday, as hundreds of ReTs assembled at Residency Road and began marching towards the civil secretariat, police fired dozens of tear smoke shells to chase them away. Dozens of policemen were seen running after teachers and beating them with canes. Dozens of them were injured. The bustling civil lines area appeared to be battle-ground for several hours until the protesting teachers got exhausted and subsequently dispersed.
