Four persons were arrested in connection with the murder of a retired private school teacher at Muniyanthangal village near Kannamangalam in Tiruvannamalai district on Sunday.
The dead dog and the way the woman was killed while seated alerted the police to the fact that the murder must have been committed by somebody known to the victim. A special team formed for the occasion investigated those occupying nearby shops owned by Lourdu Mary.
When the police questioned Illyas, 30, a butcher, his contradictory answers resulted in the police grilling him further following which Ilyas confessed to having killed the teacher with three others to steal her jewels.
Based on his confession, the police arrested Yusuf, 34, Musa, 40, and Vijaya Kumar, 30, from nearby locations. The arrested were remanded in custody at Vellore Central Prison.
