Ayumu Iwasa topped Formula 2 Monaco practice session that was red-flagged three times due to crashes.
Iwasa went fastest with a time of 1m22.081s, 0.046s quicker than previous pacesetter Victor Martins, inside the final two minutes of the 45-minute session.
Running was then brought to an early halt by the third and final red flag of the session after Richard Verschoor – who was third-fastest at the time – found the barriers at Portier.
Ollie Bearman, who both races on the streets of Baku last time out, earlier crashed in exactly the same place to bring an early end to his first ever session in Monaco.
The strangest incident however had come within the first 10 minutes when Ralph Boschung and Roman Stanek collided with each other and then the barriers at the final corner, ending both their sessions.
Martins, who last drove in Monaco three years ago in Formula Renault Eurocup, originally went fastest with seven minutes left on the clock and found a further improvement a couple of laps later.
Arthur Leclerc, driving his home streets in anger for the first time, set the fourth-fastest time behind Verschoor and ahead of Dennis Hauger.
Enzo Fittipaldi took sixth in front of Jack Doohan, who had set the pace at the time of Bearman’s crash in the middle of the session. Kush Maini and Frederik Vesti came next with Theo Pourchaire, a former polesitter and winner in Monaco, a relatively quiet 10th.
