Ryan Farquhar is one of the riders in the Ulster Grand Prix

Thursday morning's Ulster Grand Prix practice session was held up after an angry local resident parked her car close to the course in a protest.

The woman left her vehicle on her own property close to the Budore section of the Dundrod circuit in a dispute with race officials.

The Dundrod 150 road races were held as scheduled later on Thursday with a number of extra safety measures.

Hay bales were put around the vehicle and yellow flags used to warn riders.
