A Malda Court on Thursday pronounced life imprisonment to two persons for killing a woman teacher at the English Bazar area of Malda in April 2011.
Prince Ghosh and Rajkumar Rishi killed the teacher by sending a parcel bomb to her house.
The victim Aparna Biswas (30) a teacher of Ramkinkar Balika Vidyalaya used to live in a rented house at Malanchapally.
The accused had delivered a parcel bomb to the victim who opened the parcel at around 12 noon on April 25, 2011.
When she opened the parcel, the bomb exploded. The victim died on the spot.
Police came to know after interrogating the courier agent, that the parcel was booked from Gajole on April 22.
There were repeated calls from a particular number insisting a quicker delivery. After examining the phone number, the police learnt that the phone belonged to one Prince Ghosh of Mangalbari under Malda Police station.
He was then taken into custody and after interrogation it was learnt that Prince had an affair with Aparna for years. He later hatched the plan after she ended the relationship.
The accused since then made up his mind to avenge the refusal.
Prince Ghosh and Rajkumar Rishi were sentenced on the basis of Section 302 (Murder), 201 (tampering of Evidence), 34 (common intention) IPC and 3 In 4 Indian Explosive Act.
