Max Verstappen has been summoned to the stewards for an alleged red-flag breach during second practice for the Dutch Grand Prix.
The session was halted after just five minutes when Lewis Hamilton sustained an abnormal oil pressure issue and was ordered by Mercedes to stop his car.
As red flags were being shown, television footage showed Verstappen overtaking Aston Martin's Lance Stroll between turns 10 and 11.
Verstappen and a team representative have been requested to report to the stewards at 10:45am local time [9.45am BST].
If the stewards deem Verstappen to be guilty of the offence then he faces a potential grid penalty for his home race at Zandvoort.
