Range & District Police
Outside the Dhaka capital region and other metropolitan cities, police is organised into Police Ranges, headed by a Deputy Inspector General of Police (DIG), who control several Police Districts. Now there are seven Police Ranges in seven administrative divisions and two Police Ranges for railways and highways.
The Police District is the fulcrum of police activity and each Police District is headed by a Superintendent of Police (SP).
The Police District is made up of one or more Circles, and is under the command of an Assistant Superintendent of Police (ASP) often referred to as the Circle ASP.
Under the Police Circles are the police stations, generally under the control of an Inspector of Police who is called Officer-in-Charge (OC). Under him several Sub-Inspector of Police works. As per the various Bangladeshi laws, Sub-Inspector (and above) are the only officers who can file a charge sheet in the court.
Each Police Range maintains its own Range Reserve Force (RRF) and district police also maintains its own Special Armed Force (SAF) which is responsible for emergencies and crowd control issues. They are generally activated only on orders from the Superintendent of Police, and higher-level authorities. The armed constabulary do not usually come into contact with the general public unless they are assigned to VIP duty or to maintain order during fairs, festivals, athletic events, elections, and natural disasters. They may also be sent to quell outbreaks of student or labor unrest, organized crime, and communal riots; to maintain key guard posts; and to participate in anti-terrorist operations.
