Rapid Action Battalion (RAB) arrested the prime suspect in the murder of schoolgirl Jesika Mahmud Jesy in the capital’s Wari neighbourhood on Saturday night.

The arrestee is Bijoy Rahman, 19, son of Arifuzzaman Arif, of Munshiganj sadar.

The officer said that the tenth grader died at Bijoy’s house at Courtgaon in Munshiganj on January 3. Her elder brother filed a murder case at Munshiganj Sadar Police Station on January 4.

During preliminary interrogation, Bijoy said that he engaged in a romantic relationship with Adiba in 2019. Later in 2022, he was also               romantically involved with Jesika.

In February 2022, he got married to Adiba secretly, but Jesika discovered it later.

In the meantime, Adiba found out about her husband’s relation with Jesika, which provoked her to take revenge on Jesika.

Later, Adiba and her husband called her to their house where they suffocated her to death.
