Police want to identify this man, pictured, who is thought to have trespassed onto the TT course during racing yesterday evening - narrowly missing the leading riders at the start of the second lap.
Police say the incident occurred at Bray Terrace, Bray Hill, Douglas at about 6.40pm. They are appealing for the man, or anyone who can identify him, to come forward.
It's the latest in a series of reports of people walking on to closed roads. Yesterday, a man was jailed for eight weeks and banned from the Isle of Man for venturing on to the TT course while roads were closed.
