The Metropolitan Police is reportedly investigating a catalogue of vile internet abuse targeting the family of Madeleine McCann including death threats. An exclusive report by Sky News says officers are in talks with the Crown Prosecution Service after being handed a dossier of more than 80 pages of Tweets, Facebook posts and messages on online forums aimed at Kate and Gerry McCann.

Sky News further revealed that the Metropolitan Police is investigating a catalogue of internet abuse targeting the family of Madeleine McCann including death threats.

A series of messages have been posted in recent years pointing to the involvement of the parents despite both Portuguese and British police saying they are not suspects.

Some of the messages posted by so-called internet trolls include suggestions that the McCanns should be tortured and killed and calls for them to “burn in hell”.

Some messages are even directed at Madeleine’s younger siblings, now aged nine, Sky News said.

In Portugal, sources close to the case said this week that detectives from Scotland Yard should arrive in Portugal in the coming week or so for another routine meeting with their Portuguese counterparts in Faro.

This meeting will then be followed by further inquiries in Portugal after a request was sent to Portugal at the end of August for further questioning of suspects in the Algarve.

It is understood the officers have been granted permission to interview up to seven key suspects identified earlier this year – three of whom are expected to be questioned for a second time.

This is the fifth such letter to be received by Portuguese authorities since last October.

Last month, British detectives admitted upon their return to the UK that “no evidence relating to Madeleine McCann had been identified.”

Sources close to the case had earlier told The Portugal News: “Unfortunately we are nowhere nearer to solving the case than we were seven years ago” even though it appears the investigation is far from over.
