Munna Bajrangi was initially a carpet weaver. After a few independent killings, the first at the age of 17, he committed the first murder. he joined a gang in Uttar Pradesh led by Gajraj Singh. In an atmosphere where the moves of criminals becoming politicians was pioneered by gangsters like Brijbhusan Sharan Singh, Raja Bhaiyya, DP Yadav and others, Bajrangi started his criminal career as a member of criminal-politician Mukhtar Ansari's gang. In the early 1990s, under the governance of Mulayam Singh Yadav's Samajwadi Party, criminals were flourishing in UP. In 1996, Mukhtar was elected from Mau, and the gang, with its arsenal of AK 56and other weapons, became a household name in the districts of Bhadohi Mau, Ghazipur, Varanasi and Jaunpur. The gangs made a living by garnering government contracts with political help. They soon came into conflict with Brijesh Singh, another established ganglord who worked together with politician Krishnanand Rai of the Bharatiya Janata Party. In 2001, Brijesh Singh's gang ambushed the Mukhtar Ansari gang on the Mau-Lucknow highway; three people died from each mafia gang. In the 2002 elections, Mukhtar's brother Afzal Ansari, who had won from Mohammadabad in five earlier elections, was defeated by Krishnanand Rai, a rival politician supported by the Bharatiya Janata Party. On the afternoon of November 2005, Rai was travelling with six aides when they were attacked by seven gangsters in a Tata Sumo. Bajrangi along with associates Firdaus, were Ata-ur-Rahman alias Babu, and Aijazul Haque were identified by some survivors. CBI later identified Vishwas Nepali, Sanjeev Maheshwari, Rakesh Pandey and Ramu Mallah as the other members of the attacking team. Over 400 bullets were fired from six AK-47 rifles, killing Rai and all others travelling in two Qualises. 67 bullets were recovered from seven bodies. A police officer called it the largest "display of firepower" in an Uttar Pradesh mafia battle. Since then, Bajrangi was on the police's most wanted list. In 2009, after announcing a cash reward of Rs.700,000, Bajrangi was arrested against from the Shanty Siddivinayak Residential Society in Mumbai's Malad area. He had been living in the apartment under his real name, Prem Prakash Singh, along with his wife and three teenaged children since 2003.
