The way the Met Police initially handled the deaths of four men murdered by serial killer Stephen Port is to be re-investigated by the police watchdog.
Port is serving a whole-life sentence for the murders of Anthony Walgate, Gabriel Kovari, Daniel Whitworth and Jack Taylor in Barking, East London.
The deaths were not seen as suspicious until weeks after the final murder.
"Basic failings" were identified at an inquest last year in the way the police handled the four men's deaths.
In 2019, the police watchdog, the Independent Office of Police Conduct (IOPC), decided no officers had a case to answer for misconduct or gross misconduct as a result of the failures to catch the serial killer.
Now the IOPC has said there were "material flaws" in its own investigation.
