Police have used water cannons and stun grenades to disperse a rally of teachers demanding the inclusion of non-MPO educational institutions under the monthly-pay-order scheme. Police blocked their procession, then used water cannons and sound grenades to disperse them. The teachers have been demonstrating under the Non-MPO Shikkha Pratishthan Oikya Parishad’s banner since Nov 3 outside the National Press Club. Teachers of recognised non-MPO educational institutions have long been demanding MPO inclusion. They initially began their sit-in on Feb 23 outside the National Press Club and continued for 17 days.
