While four people, including two Chinese nationals, had earlier been arrested in the case, the new suspects have been identified as S Manoj Kumar, S K Muthukumar, K Jagadeesh and A Sigasudhin.
Among them, Sigasudhin was a territory sales manager of Vodafone and Jagadeesh was an agent. They were approached by Manoj Kumar and Muthukumar — who runs a software development and digital marketing firm in the city with a branch in Bengaluru — and bought 1,100 SIM cards by using fake documents.
Sigasudhin too issued the SIM cards without verifying the documents, said the police. During interrogation, Manoj Kumar and Muthukumar allegedly said that they were approached by a woman called Ria Gupta on Facebook requesting them to supply 1,100 SIM cards on a commission. These SIM cards were used in the call centres run by the Chinese nationals to make calls and harass those who borrowed money from loan applications.
