Kolkata: The 28-year-old man, Raju Naskar alias Napit, who was arrested on Tuesday for killing Somnath Chakraborty (42) on Sarat Bose Road with a stone, is being interrogated by cops for his ‘possible involvement’ in several other cases in south Kolkata.Police on Wednesday said Naskar, a beggar, confessed to stabbing another person under Lake PS area last year. He reportedly attacked people with a blade on a couple of occasions in southeast Kolkata, said an officer. “We are looking into his past cases. We will know about his involvement in other cases within a day or two,” said DC (south) Priyabrata Roy.An officer said Naskar was also being questioned for a murder case that was reported near Park Circus. The case is now ‘cold’. No one was arrested. “That victim, too, was found with his head bashed in with a stone,” said an officer.In the Sarat Bose Road murder case, cops said Naskar patiently waited for three days to look for an opportunity to kill Chakraborty. “The accused was apparently upset over sharing a Rs-100 note received as alms. After the argument, Naskar lay low for a couple of days and then, took his chance on Monday night,” said an investigating officer. He added that while Naskar confessed to his crime, he hardly showed any remorse or guilt about the entire episode.Cops are likely to use the gait pattern technology to establish the presence of the accused in the earlier cases. Police are also trying to recreate the crime scenes and are planning to take Naskar to these locations for further investigations.The body of the Sarat Bose Road victim, Somnath alias Bumba, a resident of Dakghar in Maheshtala, who used to do odd jobs in south Kolkata, was discovered by a tea stall owner, Sudhir Giri, on Tuesday morning outside Sudesh Bhawan on Sarat Bose Road. His body bore severe head trauma, a fractured right hand and blood was oozing out of the left ear.
