Severely injured Zobayed had sought help knocking on Barsha鈥檚 door but she refused to assist and then he died due to excessive bleeding, said police.
Briefing reporters at Dhaka Metropolitan Police media centre on Tuesday, DMP additional commissioner (crime and operations) Nazrul Islam said that Mahir and Barsha had been in a relationship for about one and a half years.
Later, Barsha developed a romantic relationship with Zobayed, which Mahir could not accept.
Following repeated disputes, Barsha instigated Mahir to kill Zobayed, he said.
Mahir then shared the plan with his friend Aylan and the two bought a switch-gear knife at Tk聽500 from Bowbazar in South Keraniganj, he said.
鈥極n the day of the incident, Barsha informed Mahir when Zobayed would arrive at her house for tuition. As soon as Zobayed reached the building, Mahir confronted him and stabbed him in the neck during an altercation,鈥� said Nazrul Islam.
Deputy commissioner of Lalbagh zone Mallik Ahsan Uddin Sami, who was also present at the press conference, said that Barsha confessed that Zobayed鈥檚 last words were, 鈥楽ave me,鈥� to which she replied, 鈥業f you don鈥檛 move away, I can鈥檛 be with Mahir.鈥�
Police later conducted operations in South Keraniganj, Paltan and Bangshal areas and arrested three accused on Monday night.
The arrested are Md Mahir Rahman, 19, Barjis Shabnam Barsha, 19, and Fardeen Ahmed Aylan, 20.
The murder took place around 4:30pm on Sunday in Noor Box Lane area under Bangshal police station in Old Dhaka.
