Lily Robotics, which promised a autonomous flying camera, is shutting down operations. Lily Robotics, a failed drone startup that closed last month amid a consumer-protection civil suit from the San Francisco District Attorney's office, may now be the subject of a criminal investigation. Earlier this month, law enforcement agents raided the company's San Francisco headquarters for a potential criminal investigation against the company, according to one source who asked to remain anonymous because they were not authorized to speak openly about the matter. When contacted by FORBES about the visit from law enforcement individuals, Henry Bradlow, Lily Robotic's cofounder and chief technology officer, said he could not comment "on rumors or speculation" and hung up the phone. A spokesperson for the San Francisco District Attorney's office said that he could not confirm or deny if a raid had occurred.
