A Manipur court on Friday sent Asian Games gold medal winning boxer Dingko Singh to 15 days judicial custody on charges of assaulting a 17-year-old girl athlete and outraging her modesty. The Arjuna awardee boxer was arrested late Thursday. ‘Dingko surrendered to police on Thursday evening after family members of the female athlete registered a case against him,’ police said. Police said the incident took place Jan 13 at the Khuman Lampak Sports Complex in Imphal. Dingko alleged she had scribbled his name on his car’s dust-covered registration plate. Dingko allegedly paraded all players of the complex and asked them to write his name on a piece of paper. Subsequently, he singled out the girl and claimed it was she who had scribbled his name. The girl alleged Dingko hit her with a stick in a brutal manner. She also received treatment at a private hospital in Imphal.
