Inflammatory, hate-filled posts provide a disturbing insight into the beliefs of the man behind a horrific fire-bomb attack on an immigration centre.

Andrew Leak, who took his own life on Sunday after targeting a site for asylum seekers in Dover, was named for the first time today by police.

Counter-terrorism teams have also been brought in to investigate the 66-year-old, whose social media profile is littered with tirades against asylum seekers, Muslims and the royal family.

The rambling posts lash out at a number of minority groups and suggest people should "stand up".

One reads: "Yet the next time the job centre sanctions your money for not looking for enough work asked them about the thousands of people getting benefits cannot speak English can not write English how are they looking for work 4 times I have put in freedom of information request how many people cannot speak English right English Are receiving unemployment benefits clearly States you cannot claim benefits if not looking for work all of these people should be excluded from benefit."

Another post says: "Last night last night I was reading probation reports for Muslims who are going home to live with children young girls probation officer stated that them young girls are safe if because the husband only raped non-Christian children what the f*** is going on in this country

"This will all be released soon they are sending Muslims home with young girls because they're safe because the man only rapes non-muslim children they're getting parole on this f****** report what the f*** a quarter of a million children groomed in this country still going on today probation please I'll let it happen a big report will be released soon if they don't do what they're told to do will be the end of England."

In others, he appears to lash out at the Royal Family, with a post dated before the Queen's death reading: "Prince Chiles Says hes going to house Ukrainian refugees in one have his properties that belong to the British people what about soldiers and members of the public sleeping in doorways disgrace in the End Royal family family now."

In the months before Leak drove more than 100 miles from his home in High Wycombe to carry out the attack in Kent he also told his Facebook friends: "I am near the end of my journey."

Anti-terror officers have been drafted in after a raid at Leak's home uncovered "a number of items of interest", including "digital media devices".

Shortly after the horrific attack, Leak's body was found in his white SUV at a petrol station a short distance away from the scene.

Police moved to reassure the public that "there is currently nothing to suggest the man involved was working alongside anyone else, and there is not believed to be any wider threat to the community in the High Wycombe area or in Dover."
