A right to information activist who had exposed scams in various Bihar government schemes was killed by unidentified assailants in East Champaran district on Tuesday. The assailants, who were on a bike, shot Rajendra Singh three times while he was on his way back from meeting his lawyer in Motihari town, The New Indian Express reported, citing police officials.

Singh had survived at least three attempts on his life in the past, the daily said. “Some locals saw him lying in a pool of blood on the road [on Tuesday]. He was rushed to Motihari Sadar Hospital, where doctors declared him brought dead,” Piprakothi Station House Officer Abhishek Ranjan said.

Singh had helped expose discrepancies in the functioning of an LIC office, irregularities in the recruitment of teachers and police personnel, and misuse of funds under the Indira Awas Yojana housing project, News18 reported.

“Rajendra had survived an attack by an unknown man on a road last year. A jeep had hit him mysteriously in 2015, and he was attacked at his home in 2012,” the deceased’s son-in-law RK Singh said. Government authorities had ignored Rajendra Singh’s requests for security, the son-in-law added.

Two mobile phones belonging to the deceased were found at the spot where he was shot. “He had spoken to someone a few minutes before being shot,” Sadar Deputy Superintendent of Police Murli Manohar Manjhi said. “An investigation is on, and we are looking at all angles.”

The Rashtriya Janata Dal has accused Chief Minister Nitish Kumar of failing to maintain law and order in the state and demanded an inquiry.

This is the second such incident in the state in two months. Another RTI activist Jayant Kumar was shot dead in Vaishali district on April 4. In March, activist Poipynhun Majaw was found murdered in the Khlierhriat area of Meghalaya.
