The hunt for the suspect in the killing of Brian Thompson, the CEO of UnitedHealthcare, has entered a second day – and New York police issued a fresh image clearly showing the face of a man they are looking for in connection with the shooting.

Thompson, who ran one of the the US’s largest health insurers, was fatally shot on Wednesday in midtown Manhattan. Shell casings found at the scene reportedly had the words “deny”, “defend” and “depose” written on them.
