A 47 year old man from Bristol has been sentenced to eight weeks in custody and excluded from the Isle of Man.
David Seager was arrested for being on closed roads and committing a public order offence. He appeared in court today.
Police Inspector Derek Flint said: 'This sentence should send a crystal-clear message that anti-social behaviour towards fellow spectators and marshals, as well as being on closed roads contrary to a road closure order, will simply not be tolerated.
'Behaviour of this sort puts people at huge risk, and we will do everything in our power to ensure the marshals difficult job is supported.
'Anyone thinking of disregarding a road closure order should take heed, and be mindful that the courts will take a similarly dim view of such irresponsible action.'
