A 21-year-old man is in police custody after driving his road car on to Brands Hatch circuit during a race.
The man, from Tonbridge in Kent, made his way through the paddock and on to the track via the pit exit, driving almost a full lap in his Volkswagen Polo before returning to the pits.
The Fun Cup race being run at the time was red flagged due to the incident.
In one video, shot on a cameraphone from the car's back seat, the driver laughs and jokes as he makes his way on to the track. A female passenger can be heard begging the driver to stop, but he ignores her and continues on to the circuit.
Former F1 driver Jonathan Palmer, who is chief executive of the MotorSport Vision group that owns Brands Hatch, says he hopes the man is adequately punished for his actions.
"I'm absolutely seething at this complete madness," Palmer told Autosport. "It was deliberate and endangered competitors and his passengers.
"It's a completely unprecedented occurrence, an opportunity to get a bit of notoriety.
"We're co-operating already with Kent Police. It's very important the law takes a strong stance to make it clear it's not acceptable."
A Kent Police statement released yesterday said: "On Sunday 15 June, Kent Police was made aware of a report of possible offences committed at Brands Hatch race track in West Kingsdown.
"Officers have today (Monday 16 June) arrested a 21 year old man from Tonbridge on suspicion of false imprisonment. He remains in police custody."
