Kent Police said the suspect in Sunday’s attack was Andrew Leak, 66, from High Wycombe in Buckinghamshire. He was found dead at a nearby gas station shortly after the attack. Police stressed that they had not classified the attack as terrorism at this stage, but the knowledge and tactics of specialist investigators were now deemed necessary as the case developed. DCS Olly Wright, head of counter-terrorism policing in the south east, said: “What seems clear is that this despicable offense was targeted and possibly driven by some form of hate-filled grievance, although this may not necessarily meet the threshold of terrorism. “At this point, the incident itself has not been classified as a terrorist incident, but this is being reviewed as the investigation progresses.” Police said counter-terrorism officers had been helping the investigation from the start, as the Guardian understands it has MI5, the security agency leading the fight against the threat of extreme right-wing violence. The spill reached the center and “a number of crude incendiary devices were thrown out and into the premises by a man who arrived at the scene, alone in a car,” police said today. Leak was found dead in the car nearby, with two staff members at the center suffering minor injuries. On Tuesday, police said a search of a property on Monday in the High Wycombe area, 118 miles away, linked to the leak, yielded interesting results: “A number of items of interest were recovered, including digital media devices, which are being examined as soon as possible. “Due to the nature of the evidence gathered so far, it is clear that officers with specialist knowledge, resources and experience are best placed to lead this work to identify motivating factors.” Police added: “There is nothing to suggest that the man involved was working with anyone else and there is not believed to be a wider threat to the community in the High Wycombe or Dover area.” Wright added: “This has been a traumatic incident for all involved, and the wider community, and we are working hard to establish exactly what led to the events of Sunday morning.

Pictures of the suspected attack showed a man releasing a plastic bottle stuck to a lit firework at the Western Jet Foil in the port of Dover, where Border Force officers process people who have crossed the Channel in small boats. The suspect was confirmed dead shortly after the incident. For an act of violence to be treated as potential terrorism, there must be a belief that it may have been politically or ideologically motivated. Speaking in the Commons on Monday, shadow home secretary Yvette Cooper asked if counter-terrorism officers were investigating the incident. “There’s no point in not being,” he said.
