Kanchipuram: A group of people decided to clean the premises, especially the pond in the Gangaiamman Temple of Manamathi, Kanchipuram district in Tamil Nadu. 

A mysterious substance that they came across exploded. One died and four others are injured. 22-year-old Surya succumbed to injuries. Jayaram (28), Dileepan (25), Yuvaraj (25) and Thirumal (22) were severely injured. They have been admitted in Chengalpattu Government Hospital. 

This comes in the wake of intelligence inputs on the issue of infiltration of suspected LeT terrorists into Tamil Nadu. Coimbatore continued to be under tight security for the third day on Sunday (August 25) too, with places of worship especially churches being brought under increased vigil.Also read:
