Dover migrant centre attack driven by right-wing ideology - police- PublishedThe firebombing of an immigration processing centre was motivated by extreme right-wing terrorist ideology, police have said.Andrew Leak, 66, from High Wycombe, Buckinghamshire, threw up to three incendiary devices at the site in Dover, Kent, last Sunday.Tim Jacques, senior national co-ordinator for counter terrorism policing, said: "After considering the evidence collected so far, whilst there are strong indications that mental health was likely a factor, I am satisfied that the suspect's actions were primarily driven by an extremist ideology.Following the attack about 700 migrants were transferred from Dover to the processing centre at Manston, where overcrowded conditions had already been severely criticised by government inspectors.A police statement on Saturday said: "A number of significant witnesses have been spoken to during the course of the investigation and a number of items of interest have been recovered, including digital media devices."
