The FIA have launched an investigation to find out why a race marshal was on track following the restart of Sunday's Singapore GP.
Carlos Sainz and Nico Hulkenberg's collision at the start of the race resulted in a Safety Car period but as leader Nico Rosberg was given the green light to start racing again, a marshal was sprinting to the side of the circuit.
A spokesman for Formula 1's governing body told Autosport that procedures were not "properly executed" by the clerk of the course and team of officials and that they were taking the matter "very seriously".
The marshal was running across the track after picking up debris as cars approached Turn One, and Mercedes boss Toto Wolff added that "it was very dangerous".
The Austrian said race control had been asked to re-start races sooner, rather than cars having to spend too long behind the Safety Car, and that request had been heard. Rosberg, meanwhile, said the incident had been "pretty hairy".
"I think just as we didn't expect the restart, he didn't either," the eventual winner in Singapore said. "Because the restart was somehow pretty abrupt.
"But he got out of the way just about in time so it was OK. Of course we all had to drive a bit carefully through there."
