Police sources have said they were gagged from releasing key information about Southport killer Axel Rudakubana.

Detectives from Merseyside Police had wanted to provide details about Rudakubana's background, including his religion and his crimes, but were warned not to do so by the Crown Prosecution Service (CPS).

Sources had also been keen to elaborate on a terrorist document and batch of ricin found at his home but were advised against it, reports The Telegraph.

Rudakubana pleaded guilty to themurder of Alice da Silva Aguiar, nine, Bebe King, six, and Elsie Dot Stancombe, seven, at a Taylor Swift-themed holiday club on July 29 last year.

Rudakubana pleaded guilty to the three murders earlier this week

A police source said there was frustration among those working on the case that they were being prevented from saying more.

They told The Telegraph: "As far as they are concerned the more information that is in the public domain the better as it negates the speculation and conspiracies."
