Four members of a family, including a former schoolteacher, were killed at their home in Rangpur city after they reportedly objected to two young men consuming Yaba on their rooftop, police said on Sunday.

The victims were identified as Ganapati Chakraborty alias Jewel (65), a former teacher of Rangpur Zilla School; his wife Pritilata Chakraborty (50); their daughter Parthi Chakraborty Agami (25); and their son Priyam Chakraborty Ayush (12), a Class V student at Rangpur Zilla School.

Rangpur Metropolitan Police Commissioner Mohammad Abdul Mabud shared details of the murders during a press conference at his office on Sunday morning following the early morning arrest of two suspects.

The arrestees were identified as maternal cousins Mugdha Das (23) and Siddhartha Das (19).

According to police, officers recovered the bodies from different locations in the house, located in the city's Machuapara Mandir area, around 11:30 pm on Saturday.

One body was found on the rooftop, two on the terrace, and another inside a room.

Mabud stated that Mugdha and Siddhartha accessed the rooftop of Ganapati’s house via an adjacent building on Thursday night to consume Yaba.

Hearing noises, Ganapati went upstairs and caught the duo taking the drugs. When he objected, the two suspects allegedly strangled him with a 'gamcha'.

Hearing her husband's screams, Pritilata tried to go upstairs but was killed on the staircase, the police commissioner said.

The suspects then killed the daughter, Parthi, and finally 12-year-old Priyam.

Mabud explained that Priyam knew the suspects and was a friend of Siddhartha’s younger brother, Apurba.

Fearing the child could identify them, the suspects killed him as well.

Following the killings, the two suspects remained inside the house, where they allegedly took showers, ate dates, and consumed more Yaba.

They left the premises during Jummah prayers the following day while the streets were relatively quiet.

Before departing, the suspects scattered household items to simulate a robbery and mislead investigators, the commissioner added.

A breakthrough occurred when investigators found a gold bangle at the scene showing signs of a fire test.

This led police to learn about Siddhartha’s background as a goldsmith. Police detained Siddhartha and Mugdha early Sunday morning, during which both confessed to their involvement.

Siddhartha has reportedly worked as a goldsmith at PK Pal Jewellers for about eight years, while Mugdha works at a fish shop in the city’s City Bazar.

The looted jewellery was subsequently recovered from an abandoned location based on information provided by the suspects.

Additionally, two mobile phones belonging to the family were found submerged in detergent-mixed water, which police said was done to destroy evidence.

Investigators also gathered evidence of Yaba consumption, date seeds, and a partially eaten cucumber from the scene.

The date seeds have been submitted for DNA testing.

Mabud noted that Mugdha and Siddhartha had consumed Yaba at another location in the city before moving to Machuapara, where they took the drug again.

Police have also identified a suspect named Khushi alias Prashanta as the alleged Yaba supplier and are verifying the lead.

A murder case has been registered at Kotwali Police Station.

Police confirmed they are working to conclude the investigation and submit the charge sheet to the court as quickly as possible.
