Realtor Kalyan Roy, alias Nantu, was arrested on Friday in connection with the murder of his friend Kunal Bose in 2000.
Bose, an executive with Metal and Scrap Trading Corporation, was found critically injured in a ditch off the Bypass on May 26, 2000. He died later.
Roy and Boseís wife Aparajita (Moon Moon to her family) were arrested in connection with the murder and sentenced to life imprisonment. The high court acquitted Aparajita in December.
Royís appeal against the conviction is still pending but the high court had granted him bail in 2005.
ďThe high court while acquitting Aparajita had asked Roy to surrender in two weeks. Roy did not do so, prompting the court to issue an arrest warrant against him. We have executed the warrant by arresting Roy,Ē said joint commissioner (crime) Pallab Kanti Ghosh.
