PUDUCHERRY: Two 18-year-old students lost their lives after getting trapped in the deep silt of a check dam near Villianur in Puducherry on Friday. The deceased have been identified as K Vignesh of Thiruvandarkoil near Puducherry and G Kabilesh from the Kalitheerthalkuppam. Both boys had recently completed their Class XII examinations and were waiting to secure college admissions. Police said the duo, along with three other friends, went to the check dam built across the Kuduvaiyar river at Melshathamangalam near Villianur to take a bath. While they were swimming, Vignesh unexpectedly stepped into a deep patch of thick silt and mud at the bottom of the check dam and began to struggle. Seeing his friend drowning, Kabilesh rushed to his rescue. Kabilesh also got entangled in the heavy silt, and both boys quickly sank beneath the water.
