A 22-year-old man has been jailed for six years after planning to fight with Isis in Syria.
Mubashir Jamil, 22 and from Luton, was found guilty of preparation of terrorist acts last month.
The Old Bailey heard that between November 2015 and April 2016, Jamil sent numerous online messages to people he believed could help him in his endeavours, including a covert police officer.
Jamil told the officer about his dreams of travelling to Syria to fight for Isis and his intention to get fit ahead of his journey. He bought a punchbag and pull-up bar but told the covert officer he was cautious of drawing attention to his fitness programme and had bought a football to play with "so it's less suspicious".
Before deciding to travel to Syria, Jamil considered other options, including carrying out a suicide bomb attack. He talked of wanting to see attacks similar to those in Belgium and Paris.
In one message, he wrote: "I am saying if you guys can send me someone quickly, and he fits a explosive [sic] belt on me and tells me how to press, I can go find good targets on the same day and press it."
But Jamil decided to pursue his plans to fight in Syria instead. On April 9 he booked a ticket to fly to Turkey three weeks. However officers arrested him on Wednesday April 27, before he could travel.
They seized his iPhone and two laptops from his home. These featured pro-Isis documents including How to survive in the West - A mujahid guide and The Islamic State 2015, as well as a copy of his flight tickets.
They also seized approximately £1,000 cash - found in his bedroom - under the Police and Criminal Evidence Act.
Commander Dean Haydon, head of the Met's counter terrorism command, said: "I am pleased with this result which has ensured that a man who was seemingly inspired by the terrorist atrocities in Belgium and France has been taken out of the community.
“The community is really key to our efforts to continue putting people engaging in terrorist activity before the courts. I urge the public to do this by being vigilant and reporting anything suspicious, including if they think someone they know is being radicalised."
Detective Superintendent Glen Channer, from the Eastern Region Special Operations Unit Counter Terrorism Policing said: "Luton is a fantastic town with great diversity and strong communities. However, this case shows how vigilant we must be to identify and weed out those individuals with extreme views of any kind.
“We simply will not tolerate those who spread fear and hate in our communities and will continue to target, arrest and disrupt anyone involved in such criminality. Communities play a crucially important role in defeating terrorism and I would urge people to report any suspicious behaviour via the anti-terrorist hotline.”
Anyone who notices suspicious behaviour or is concerned that someone they know is being radicalised is urged to call the confidential Anti-Terrorist Hotline on 0800 789 321 or seek help and advice from a wide range of agencies at http://www.preventtragedies.co.uk
