Speaking to the media here on Friday, Malli, mother of the slain youth Madhu, said: "It was yesterday (Thursday) evening that my son was beaten up by a group of people in the forest (near Attapadi-Agali) saying that he was a thief. Then he was handed over to the police and soon he developed complications. He was taken to a hospital, where he died. He is not a thief, instead he was not of sound mind," said the grieving mother.
