A since-deleted statement released by the Vegas race on its social media platforms read: "Due to logistical considerations for our fans and our staff, we have made the determination that we will be closing all Las Vegas Grand Prix fan areas at 1.30am. We look forward to welcoming fans back later today for exciting FP3 and qualifying sessions".
The development meant the FP2 session took place in front of empty grandstands and finished at 4am, the time the sections of track that take in public roads were supposed to be fully open to the public.
