The first practice session at Imola has been red flagged with 20 minutes to go, as a result of a bizarre incident between Red Bull's Sergio Perez and Alpine's Esteban Ocon.
The exact circumstances are yet to emerge, due to technical issues with Formula 1's world feed for broadcasters. Footage of the incident hasn't been released, but Perez and Ocon appear to have made contact entering the Villeneuve chicane.
Perez was left facing the wrong way with a blown left rear tyre, while there was minor right front damage to Ocon's Alpine. Both clambered free under the red flag, while the cars were recovered.
