The jail authorities refused to share any details about

Guru, a former fruit merchant, was found guilty of conspiring and sheltering the militants who attacked Parliament on December 13, 2001, in which nine persons were killed.
The mercy plea of Guru, who was sentenced to death in 2002 by a special court and later upheld by the Supreme Court in 2005, was rejected by President Pranab Mukherjee on February 3.
The family of Guru residing in Sopore in north Kashmir was informed about the decision of the Government that his mercy petition has been rejected.
However, Guru's lawyers Nandita Haksar and N Pancholi said his family was not informed about the government decision to hang him.
The lawyers said the family came to know about Guru's hanging only through news channels.
"The family was not informed about the decision. They came to know only through news channels. The family is in Sopore. They cannot come due to curfew," the lawyers said.
