According to BBC News, her older brother recently admitted physically attacking her – though CBS (via UK tabloid The Daily Mail) notes that at the time, he seemed to be more concerned with how the arrest would make his family look in public. The court cleared him and his father of the charges of making death threats. Apparently, Ms. Azad is dating a Hindu fellow, and this has angered her conservative Muslim family, and most notably her brother.
AOL News has more details about the attack and death threats, as well as why Ms. Azad is refusing to testify against them.
