The murder suspect was in the audience of UN General Assembly with PM's delegation.
A Bangladeshi politician being investigated for suspected links with the murder of a Chhatra League leader in Comilla has been seen with the Prime Minister Sheikh Hasina's entourage in the US, media reports said on Friday.
Federation of Bangladesh Chambers of Commerce and Industry (FBCCI) Director Masud Parvez Khan Imran is the prime accused in the case with a member of the executive council of the Comilla Chamber of Commerce and Industry, which he had once headed, bdnews24.com reported.
Mr Imran and his brother Nasrullah Arman Khan were accused in a case over the murder of Saiful Islam, President of Chhatra League's Comilla city unit, in April last year.
"Imran is the number one accused in the case," police commanding officer Abdur Rab told bdnews24.com.
The Criminal Investigation Department (CID) is investigating the Chhatra League leader's murder.
Witnesses said Mr Imran was in the audience of UN General Assembly. He entered the gallery holding a card that identifies him as a Bangladesh representative.
Former Chhatra League leader Atiqur Rahman Pintu, another accused in Saiful murder case, was also spotted with Imran in New York.
Mr Saiful was stabbed to death during a programme on April 11, 2015, and Mr Imran was among the 22 accused in the case, bdnews24 reported.
This is not the only case that Imran stands accused of. Among the several other cases against him, he has secured bail in an arms case and in another over abduction.
The Chhatra League is linked to the ruling Awami League.
