Dreaded gangster Prem Prakash Singh alias Munna Bajrangi was shot dead inside the district jail on Monday, the police said.
He was brought to the Baghpat jail from Jhansi jail on Sunday and was to be produced in a local court on Monday in a case for demanding extortion money from BJP MLA Lokesh Dixit.
Bajrangi was also named in the killing of former BJP legislator Krishnanad Rai.
According to ADG Prison Chandraprakash, four jail personnel, including the deputy jailer, have been suspended following the incident.
The gangster’s wife had recently in a press conference alleged that conspiracies were being hatched to kill her husband.
