New Delhi: The teenaged Sports Authority of India (SAI) athlete, who tried to commit suicide on Wednesday, expressed regret at his conduct, revealing that he was "mentally tensed" which compelled him to attempt taking his own life.

Kerala's 18-year-old Nithin U, who won bronze in 2014 Youth National Championship, tried to commit suicide early on Wednesday at a SAI hostel in Thiruvananthapuram by slashing his wrist. He was taken to hospital from where he slipped away, police said.
