Be specific, if there is any legal issue involved in a dispute.

Each of the 28 states of India has a police force. The superintendence over it is exercised by each State Government. The head of the police force in the State is known as Director General of Police (DGP). The DGP is responsible to the State Government for the administration of the police force in the State and for advising the government on the police matters. 

Police units in India are well-structured hierarchical organizations. Though, there is marginal variation in the ranks and hierarchical order in the different organization, however, there is a general uniformity in this context in most of the police organizations. The rank and hierarchical structure of the police organization is as following:

Director General of Police (DGP) ↓

Additional Director General of Police (Addl. DGP) ↓ I

nspector General of Police (IG) ↓
