Police said on Wednesday that they had arrested a teenage boy in Narayangaj for allegedly killing his friend over a video game in Bagerhat.
The arrestee is seventeen-year-old Mohammad Ferdous who suffocated Sheikh Sabbir, 15, on January 9 of last year.
Ferdous was arrested in Narayanganj on January 30, said PBI Bagerhat Superintendent of Police (SP) Abdur Rahman on Wednesday.
According to the police officer, Sabbir left his house with his rickshaw van at 10 am but did not return home.
On January 17, police recovered the body of the victim from Katchna village at Mollahat upazila. Sheikh Borhan, father of the victim, lodged a murder case against unknown people with Mollahat Police Station on January 23.
A four-member team led by Inspector Ashraful Alam of the Police Burea of Investigation (PBI) began an investigation into the case.
The team suspected Ferdous, son of Sheikh Monirul of Dingcypara at Moramara in Bagerhat Sadar and finally held him at the Meghna Bridge area in Sonargaon upazila of Narayanganj.
During interrogation, Ferdous said that he and the victim played a free-fire game on two Android smartphones.
He defeated Sabbir in the game, but the victim scolded him with ill words. Then, he decided to kill him to take revenge. On the day of the incident, around 2:45 pm, he sent a child named Baezid to call Sabbir to a garage. Then they began to play the virtual game again. At one point, Ferdous came behind the victim and suffocated him to death with a gamsa (towel) and fled the scene after wrapping the body with a blanket in the garage.

The killer later sold Sabbir's van to a scrap dealer. On the following day, he went to the killing spot again and took the body to a godown owned by one Obaidur Rahman and covered it with garbage.
