The year-long suffering she faced following the controversial "gender test" in 2014 has hurt promising sprinter Dutee Chand so much so that she still feels that she may get trapped and her resurrected career may be in ruins again. Two years ago, Chand's dreams of representing her country at the Commonwealth Games and Asian Games came crashing when an indefinite ban was imposed on her, barring her from taking part in women's competitions due to her higher levels of testosterone (hormones primarily produced by male). Dutee fought the case at the Court of Arbitration for Sports in Switzerland which upheld her appeal, citing no clear cut link with higher levels of these hormones with enhancement in performance. She returned to competitions last year and broke the national record in 100m dash recently. "I'm not able to trust anyone. I am scared that I might get trapped again. I hardly have any friends," Dutee told reporters on the sidelines of the GAIL Indian Speedstar event. "I prefer to train alone at SAI camp in Hyderabad. I don't train at national camp at NIS Patiala. Some of the 4x400 relay members don't like me," she added.
