After what had been a low-key session, it sparked to life in the closing stages.
After being held up by Norris at Turn 5, Leclerc veered his car into the McLaren driver's tyre, resulting in both drivers being summoned by race stewards.
What happened to Hamilton in Barcelona?
Seven-time world champion Hamilton was involved in a similar incident, coming into contact with Lance Stroll after the Canadian deemed his rival to have hampered his progress, a move which also brought an investigation from race officials.
“This f**king guy thinks he’s alone on the track,” said an incensed Stroll over team radio, before Hamilton apologised for failing to see the Aston Martin star.
Speaking after the event, Wolff admitted he was amazed more incidents like the ones seen in Barcelona are not more commonplace, particularly in qualifying.
"I am amazed we don’t have proper accidents in qualifying, when everybody is flat out, you’ve got to do the lap, our engineers are constantly on the radio saying: ‘be careful’," he told Sky Sports.
"I don’t want to cloud this, but it’s [an accident] waiting to happen."
Addressing Stroll's comments, the Austrian added: "I can understand it in the heat of the moment sometimes, when you’re on your fast lap and being blocked.
"But it’s never the driver’s fault - we’re getting the instructions from the garage about the traffic situation, and nobody does it on purpose because you know you can have a penalty."
