Tavella murder suspects confessed to being hired for killing "a white man" to create anarchy in the country, Dhaka Metropolitan Police Commissioner Mohammad Asaduzzaman Miah said today.

"Not Tavella, they were contracted to kill any foreign national especially a white-skinned man," the DMP chief said at a press briefing at DMP media centre.

The police official was addressing the briefing after detectives arrested four suspected killers of Italian aid worker Tavella in Dhaka. They also recovered the motorbike used in the murder.

The arrestees are: Tamzid Ahmed Rubel alias Mobile Rubel alias Shooter Rubel, Sakhawat Hossain alias Sharif, Russell Chowdhury alias Chakki Russell alias Biddut Russell, and Minhazul Arefin Russell alias Bhagina Russell alias Kala Russell.

After they were paraded before the meida, a Dhaka court today placed three of the four suspected killers on eight-day remand each.

Metropolitan Magistrate Md Mahbubur Rahman passed the order after Inspector Zehad Hossain of Detective Branch of Dhaka police, also the investigation officer of Tavella murder case, produced them before it with a ten-day remand prayer for each.

Further details of the court proceedings could not be known immediately.

Bhagina Russell and Chakki Russell are convicted criminals and drug addicts, the police official said adding that they had record showing Mobile Rubel as a "cold-blooded killer". 

"We have arrested the real criminals and, by this time, collected relevant evidence and information of their crimes," Asaduzzaman claimed.

'Boro bhai ordered the killing'

"A so called "big brother (boro bhai)" ordered them to conduct the killing and we have got information about that person," the DMP official said.

"Once we arrest the so-called big brother, we will be able to arrest the persons behind the killing," he said adding that they were trying hard to recover the firearms used in the crime.

Police have not found any link to militancy and Islamic State in the murder," he said while replying to questions of the reporters at the briefing session.

The Islamic State issue brought up to hide the real criminals, he claimed.

Tavella, a project manager of Netherlands-based NGO, was gunned down in the high-security diplomatic zone in Gulshan on September 28. Two men actively took part in the killing, while a third waited on a bike ready to flee, witnesses said.

On October 18, Dhaka Metropolitan Police claimed to have unearthed the conspiracy and blueprint for the murder.

Soon after the incident, US-based SITE Intelligence Group, which monitors militant activities, uploaded a post where Islamic State purportedly claimed responsibility for Tavella's murder, but the investigators claimed that they did not find even the "slightest link" of militant outfits in it.
