Haryana /ˌhɑriˈɑːnə/ is a state in India. Constituted in 1966, it is one of two newly created states carved out of the greater Punjab province as a means of creating a stronger national identity. It has been a part of the Kuru region in North India. The name Haryana is found mentioned in the 12th century AD by the apabhramsha writer Vibudh Shridhar (VS 1189-1230). It is bordered by Punjab and Himachal Pradesh to the north, and by Rajasthan to the west and south. The river Yamuna defines its eastern border with Uttarakhand and Uttar Pradesh. Haryana also surrounds Delhi on three sides, forming the northern, western and southern borders of Delhi. Consequently, a large area of Haryana is included in the National Capital Region. The capital of the state is Chandigarh which is administered as a union territory and is also the capital of Punjab.

Sites in Haryana were part of the Indus Valley and Vedic Civilizations. Several decisive battles were fought in the area, which shaped much of the history of India. These include the epic battle of Mahabharata at Kurukshetra mentioned in the Hindu mythology (including the recital of the Bhagavad Gita by Krishna), and the three battles of Panipat. Haryana was administered as part of the Punjab province of British India, and was carved out on linguistic lines as India's 17th state in 1966. Haryana is now a leading contributor to the country's production of foodgrain and milk. Agriculture is the leading occupation for the residents of the state, the flat arable land irrigated by submersible pumps and an extensive canal system. Haryana contributed heavily to the Green Revolution that made India self-sufficient in food production in the 1960s.

A police officer (also known as a policeman or policewoman, and constable in some forces, particularly in the United Kingdom and other Commonwealth nations) is a warranted employee of a police force. In the United States, "officer" is the formal name of the lowest police rank; in many other countries "officer" is a generic term not specifying a particular rank, and the lowest rank is often "constable". Police officers are generally charged with the apprehension of criminals and the prevention and detection of crime, and the maintenance of public order. Police officers may be sworn to an oath, and have the power to arrest people and detain them for a limited time, along with other duties and powers.

Some police officers may also be trained in special duties, such as counter-terrorism, surveillance, child protection, VIP protection, and investigation techniques into major crime, including fraud, rape, murder and drug trafficking.

Responsibilities of a police officer are varied, and may differ greatly from within one political context to another. Typical duties relate to keeping the peace, law enforcement, protection of people and property, and the investigation of crimes. Officers are expected to respond to a variety of situations that may arise while they are on duty. Rules and guidelines dictate how an officer should behave within the community, and in many contexts restrictions are placed on what the uniformed officer wears. In some countries, rules and procedures dictate that a police officer is obliged to intervene in a criminal incident, even if they are off-duty. Police officers in nearly all countries retain their lawful powers, while off duty.
