Murdered tennis player Radhika Yadav's friend Himaanshika Singh said she got to know that Radhika's father Deepak was planning the murder for the last three days. "Her brother was sent away on some excuse. Her pitbull Luna would've saved her...She was also kept out of the house," said Himaanshika. "He waited for the right moment and shot Radhika," Himaanshika added.
