Twenty-three-year-old Satyam Kumar's friends are going from one government department to another in Delhi, while the Indian Embassy in Paris said that they are leaving "no stone unturned" in ensuring Kumar's body reaches his parents.
"We are expecting the autopsy reports today, but police official are saying it was an accident. We have informed the ministry of external affairs," an official from the Indian embassy in Paris told the Hindustan Times .
But in India, there is little news. "We have waited all day and gone from department to department for any information, but have not managed to get anywhere," said Avinash Kumar, Satyam's childhood friend who is in New Delhi.
"Bright young man, smiling and well integrated, he [Satyam] was considered by his peers and teachers as a serious and sociable student," said a statement by the Ecole Polytechnique.
Satyam had gone to the lake with his two friends from Indian Institute of Technology-Kanpur last Friday night after their exams were over to celebrate.
While his friends returned to their hostel rooms, Satyam stayed back. When they did not find him on Saturday, they informed the university officials and police.
