Constable Kawsar suffers from mental illness, was treated at Pabna Mental Hospital thrice, says wife
Kawsar has been placed on a 7-day remand for killing constable Monirul - both of whom were on-duty in the Baridhara diplomatic zone in front of the Palestine Embassy in Dhaka.

Constable Kawsar Ali, who reportedly shot his colleague Md Monirul to death in the Gulshan diplomatic area on Saturday night, suffers from mental illness and was treated at the Pabna Mental Hospital at least three times, according to his wife Nilufa Yeasmin.
"He suffered from psychological problems when he was stationed in Rangamati. He was later treated at the Pabna Mental Hospital at least three times in different periods. He used to take medications regularly. He has a prescription too," Nilufa told The Business Standard today (9 June).
Kawsar has been placed on a 7-day remand for killing constable Monirul - both of whom were on-duty in the Baridhara diplomatic zone in front of the Palestine Embassy in Dhaka.
Nilufa said there weren't any problems in their family life.
"He talked to his parents at around 8:00pm on Saturday. Before that, he talked to me in the afternoon. At the time, he said he had applied for leave during Eid-ul-Adha on 4 June. Said he will come home on Eid," she said.
Soon after the incident was reported, Gulshan Police Station Officer-in-Charge Mazharul Islam told The Business Standard that both policemen were on security duty during the incident.
"One of our constables, who was mentally stressed, shot another constable," he said last night.
According to Kawsar's wife, he was stressed about work. "I still can't believe he shot someone to death."
Nilufa said Kawsar had reduced communication recently. However, he had sent money for Eid shopping.
She also said they were financially solvent.
Son of freedom fighter Hayat Ali of Darerpara village at Daulatpur union in Kushtia, Kawsar is a father of two. He joined the police force in 2005. He married Nilufa in 2006.
