A “cold-blooded” nurse was trying to kill a 98-minute-old baby when she was interrupted by a doctor who had started to link her to unexplained deaths, a court heard.

Lucy Letby, 32, was standing over the incubator of a newborn girl whose oxygen levels had fallen “dangerously” low when a colleague walked in, a jury was told.
