An arsonist set fire to netting under the South Stand at Withdean Stadium early this morning.
Firefighters were called at 6.23am to a 10 square metre section of the ground where it borders a wooded area.
Sections of plastic netting burned away and dripped melting plastic into an area underneath the temporary South Stand.
That area was burning when firefighters arrived but the stand itself is not believed to have been damaged.
Anyone with information about how the fire started is asked to call Sussex Police on 0845 6070999.
