New Delhi:30 Jan 21The Delhi Police have arrested 44 people, including the man who attacked a police officer on Friday with a sword during clashes at Singhu border between Delhi and Haryana, the epicentre of the two-month long farmers’ protest against three central laws. At Ghazipur, one of the other protest sites, thousands of demonstrators dug in on the Delhi-Meerut Expressway, defying the Ghaziabad administration’s ultimatum to vacate the area. With the crowd swelling after a standoff and a tearful outburst by one of the senior leaders of the movement on Thursday, security forces in large numbers were called in again.
