Home Minister Asaduzzaman Khan today said an intelligence team is investigating the anonymous letter sent to Lalmonirhat district jail.
“Lalmonirhat jail authorities received an anonymous letter and such letters often come to jails. However, the letter has been sent to the intelligence team for its scrutiny and they are working on it,” he said.
The home minister came up with the information while talking to reporters at his ministry office.
Security has been beefed up at all the jails across the country after a convicted accused escaped recently.
All the prisons across the country have been put on high alert after some unidentified miscreants issued threats to snatch away militant prisoners from jails.
“The threats came over phone and in letters,” said a letter signed by Inspector General (IG) of Prisons Brig Gen AKM Mustafa Kamal Pasha on Sunday.
On August 7, Abu Bakar Siddique, who was sentenced to life term imprisonment, escaped from Kashimpur Central Jail-2.
