Superintendent of Police Amit Kumar Singh said that the police had some significant leads in the investigation into the murder of C. Muthusamy, a Corporation Councillor, here on November 7.
He was responding to a query on the progress in the case but did not disclose more details.
Sources in the police told The Hindu that the questioning and investigation had been primarily narrowed down to 12 persons who were either relatives or persons very well known to the deceased.
Muthusamy was said to have been involved in large scale finance business/transactions apart from his political activities.
In the early part of the investigation, the police had extensively questioned a wide section of people including those who had called Muthusamy on his mobile phone on multiple occasions in the days leading to his murder as well as the persons who had financial dealings with the deceased.
