Main drawback in Delhi police system

An estimated 20,729 Delhi Police personnel are drawing the salary of their senior rank but not getting the promotion they are entitled to, an RTI reply has revealed. The sufferers are dominantly constables and head constables but also include assistant sub-inspectors, sub-inspectors as well as inspectors- the five categories which constitute over 80 percent of the force.
