A request to put on hold the execution of the four Nirbhaya case convicts, scheduled to be hanged at 6 am tomorrow, was rejected by a Delhi court today. The Patiala court dismissed an application to stay the execution of the convicts Akshay Thakur, 31, Pawan Gupta, 25, and Mukesh Singh, 32. Pawan Gupta's curative petition was rejected today by the Supreme Court, after which he filed a mercy petition with President Ram Nath Kovind.
