In 2013, TPC killed several Maoists in an ambush and took 25 maoist as hostage. Many were released to their families by TPC. A report in The Hindu claimed that later TPC cadres handed over the bodies of Maoists to troopers of Commando Battalion for Resolute Action(CoBRA), an elite counter-insurgency wing of the Central Reserve Police Force. TPC and police officials had denied collusion. TPC spokesperson claimed CPI (Maoist) wouldn't be permitted in its territory. The area of influence of TPC is spread over the districts of Latehar, Palamu and Chatra. Five groups, including CPI (Maoist), TPC and PLFI fought for revenue in the territory. Breastfeeding and fertility  Breastfeeding and fertility are the effects of breastfeeding on the fertility of postpartum women. Hormones associated with lactation and breastfeeding can variably and unreliably inhibit processes involved with fertility. Because of the high variation of this process, breastfeeding is not recommended to be a method of contraception by medical providers. The physiological importance of this inhibition is so that women who are breastfeeding have a decreased likelihood of a subsequent pregnancy while they are still wanting to breastfeed. Breastfeeding is not a sole method of postpartum contraception that is recommended by medical providers, because it is so highly variable. There are many factors that contribute to the reliability of using breastfeeding as a method of postpartum contraception. The amount and frequency of breastfeeding, natural or artificial, affect all of these factors. Additionally, they all vary in duration and potency of their effect on fertility. The time in which a lactating woman does not menstruate is called lactational amenorrhea. Amenorrhea is the medical term that means “no menstruation.” If a woman is not menstruating, her uterine lining is not proliferating and shedding. The purpose of uterine lining proliferation is to provide a favorable environment for a potential fertilized zygote. A thick uterine lining is rich in grooves and blood vessels. The grooves increase the surface area inside the uterus, giving the fertilized zygote many different options for locations to implant. Blood vessels provide the implanted zygote with the sufficient amount of nutrients necessary for its development. Without uterine proliferation, implantation is extremely rare. The length of time in which a postpartum woman does not ovulate is another factor. During ovulation, an egg develops, leaves the ovary, and travels down the fallopian tube.
