Jailed gangster Lawrence Bishnoi was brought to Delhi's Mandoli Prison from a Gujarat jail in the early hours of Thursday, officials said.
A senior jail official said Bishnoi has been lodged in the Mandoli jail due to security reasons.
On May 2, jailed gangster Tillu Tajpuriya was stabbed to death with improvised weapons allegedly by four members of the Gogi gang inside the high-security prison.
