It's after a spate of thefts at the site
Security around the TT Grandstand and Paddock areas has been increased.
It's after a number of thefts there - including leathers belonging to John McGuinness, merchandise and a little boy's signed T-shirt.
TT officials have confirmed to Manx Radio that security measures around the site are being strengthened in response.
