Section 207(a) in Police Regulations, Bengal , 1943
(a)The object of posting an Assistant Sub-Inspector to a police-station is to relieve the investigating Sub-Inspector of all clerical and routine duties. To ensure this relief superior officers should make Assistant Sub-Inspectors definitely responsible for these duties and punishable for omissions. The Sub-Inspectors will of course exercise general supervision but should not be held responsible unless there is gross neglect all round pointing to an entire absence of supervision.
