Police officers are to be interviewed as part of a watchdog probe into how the Met handled the case of serial killer Stephen Port.

The Independent Police Complaints Commission is investigating after victims’ families called for the police to be “held accountable” over Port not being caught sooner.

Port was convicted of murdering Anthony Walgate, Gabriel Kovari, Daniel Whitworth and Jack Taylor.

He was found guilty at the Old Bailey last November and told he would spend the rest of his life in prison.

IPCC commissioner Cindy Butts said: “Over the coming weeks our investigators will be undertaking interviews with the 17 officers who have been served with notices as part of the investigation.

“These interviews are an important milestone in the investigation as we continue to build the picture of the police response to the deaths. Misconduct notices are not judgemental in any way.

“We are grateful for the information provided to us by the family and friends of Anthony, Daniel, Gabriel, and Jack, as well as members the LGBT community and the wider public, and MPS officers.

“In an investigation of this magnitude, centred upon the tragic murders of four dearly missed young men, every piece of information counts and we continue to wish to hear from anyone who can assist this important work.

“My thoughts remain with everyone affected by Port’s horrific crimes, and they can be assured that we are committed to providing them with thorough conclusions as soon as we are able.”

As part of the investigation IPCC investigators have analysed more than 700 individual documents and around 200 statements.

Following the interview process investigators will be in a position to begin preparing the final report.
