Mr. Yousuf, 21, dropped out of college to document the conflict, carrying his camera equipment around the Kashmir Valley on his grandfather’s motorbike. He was known for capturing images of riots, militants’ funerals and protests.
But in September, the career Mr. Yousuf had built came to an abrupt halt when he was arrested and accused by India’s National Investigation Agency of throwing stones as part of a campaign supported by an international terrorist body in Pakistan. Indian soldiers and police officers in Kashmir frequently face stone-throwing crowds, and the confrontations sometimes turn deadly.
The agency said Mr. Yousuf could not possibly be a journalist because he never took pictures of government development projects or of the openings of hospitals, schools or bridges.
Many journalists in the region saw the arrest as an assault on freedom of the press, pasting posters on the sides of buildings that read: “I am Kamran Yousuf. I am caged for fair journalism.”
Tarun Sahrawat, a judge in New Delhi, wrote in Monday’s order granting bail that the National Investigation Agency had failed to submit any photographic or video evidence that showed Mr. Yousuf throwing stones. The order noted that the initial charge sheet had said the stone-throwers wore masks, making them difficult to identify.
The National Investigation Agency was also unable to furnish call or chat records linking Mr. Yousuf to a terrorist organization. According to the order, Mr. Yousuf called police officers, government officials and other local journalists before he was arrested.
Alok Mittal, a spokesman for the agency, insisted that the evidence was there, adding that the trial had yet to start. In an email, he wrote that the agency had statements from “credible witnesses who had seen Kamran Yousuf indulging in stone pelting.”
Mr. Yousuf could not be reached for comment.
Mehbooba Mufti, the chief minister of Jammu and Kashmir State, wrote in a tweet that she had asked India’s home minister, Rajnath Singh, “to intervene so that the life of a young budding journalist does not get ruined.”
The Committee to Protect Journalists in New York welcomed the decision to release Mr. Yousuf on bail, which was set at about $1,550, calling on the court to drop all remaining charges against him.
“The charges against Yousuf are a clear attempt to muzzle reporting on the ongoing conflict in Kashmir and the photojournalist should never have been detained in the first place,” Robert Mahoney, the group’s deputy executive director, wrote in a statement.
