Police recovered the body of a marine engineer from the ground floor of a 10-storey under-construction building in the city's Sukrabad area on Sunday night, a day after he went missing.

A resident of Uttara, victim Rafiqul Hasan Rimon was a captain of a foreign ship, said his family members.

According to law enforcers, the body of the 42-year-old was found on the ground floor of the 10-storey building. There were injury marks on the body, suggesting that he was killed.

Police were probing family feud, enmity over possession of an apartment and Rafiqul's alleged extramarital affair with a woman as motives for the murder, said OC Atiqur Rahman of New Market Police Station.

Victim's relatives said Rafiqul recently decided to divorce his wife Kaniz Fatema.

Talking to The Daily Star, victim's father Khalil Ullah said his son sent his two children to their mother at Elephant Road through his friend Ripon around 7:50pm on Saturday after celebrating the Victory Day with them.

Rafiqul told her cousin Mitu over the phone around 9:11pm on Sunday that he was at Metro Shopping Mall in Dhanmondi, according to a general diary filed by Khalil with New Market Police Station on Sunday afternoon.

The GD said though his phone was on, nobody responded to calls from his relatives and friends on Saturday night.

Mohammad Sohag, a local chicken trader, found the victim's partially damaged iPhone in the basement of the building when he went to keep his chickens there around 9:00pm on Sunday.

Sohag claimed he inserted the iPhone's SIM card into his phone to hand it over to its owner.

“Around 30 minutes later, I received a call. Knowing about the owner of the phone, I asked the caller to come to the building,” he told The Daily Star.

Around midnight, the victim's relatives and friends reached Sukrabad and spotted the body on the ground floor of the building.

This correspondent talked to at least 20 people at nearby buildings and shops. They all said they heard nothing suspicious on Sunday and Monday.

Requesting anonymity, they alleged that many young people used to gather at the building at night to take drugs.

Victim's father Khalil Ullah yesterday filed a murder case with New Market Police Station accusing some unidentified people. He suspected that his distant grandson Sajedul Karim Rony might have a hand in the murder.

Khalil Ullah said Sajedul had been forcefully holding the possession of his son's apartment in the capital's Sher-e-Bangla Nagar and a case was pending with the court in this regard.

“I don't want the police harass someone. But I want justice for the killing of my son,” he said.

Sajedul's wife Momtaz Moina, however, said they paid Tk 10 lakh out of Tk 22 lakh, the total value of the flat, to Rafiqul, but he denied receiving any money.

The inquest report of the body, prepared by Sub-Inspector Mahbubur Rahman, cited that the face of the victim turned blackish.

The right side of the face, several fingers and elbow of the victim's right arm got smashed. There were deep scratch marks in his back and chest, it added.

Police picked up the caretaker of the building Rafiqul Islam, who sells vegetables in front of the building, for interrogation. Law enforcers also interrogated victim's wife Kaniz.

Victim's father-in-law Kamrul Islam, a retired teacher of Govt Laboratory High School, said the couple got married in 2006. Their relationship started weakening four years back as Rafiqul got involved in an affair with a girl and addicted to drug, he alleged.
