The duo was nabbed by the police, who were deployed in civil dress, from near the Tis Hazari court complex where they had gone to meet Raja's lawyer on Wednesday," the DCP said. On interrogation, it was revealed that Raja used to rent out sound systems for small functions. He had rented a sound system to Shahi for Rs 1,500 for New Year celebrations, but the payment was pending which led to a heated argument between the two. "On the night of January 29, a verbal spat again took place between Raja and Shahi on the same issue, resulting in the latter's murder by Raja and his juvenile accomplice," said Kalsi. /IANS
