The Prime Minister appeared before the SC amid tight security as 2,000 police personnel (commando, security division, traffic police), Rangers and Frontier Constabulary and lady police personnel performed security duties in the Red Zone. Islamabad Police Inspector General Bani Amin, Security AIG Majeeb-ur-Rehman and other police officers were present at the occasion. Five police prisoner vans and six armoured personnel carriers were deployed. Police officials and Rangers also patrolled the Constitution Avenue. Un-authorised people were banned from using the incoming routes to the court and only bonafide lawyers and card holders were allowed to enter the Red Zone. Three cordons of security were maintained around the Supreme Court building.
