He was given a 10 place penalty under the "totting up" rules, meaning he had infringed twice before and has 2 previous reprimands.
As for the incident.
The rules preclude it following an incident in another series. It was put in place to prevent serious injury and these two knew this full well and chose to ignore it. It was a dangerous thing to do frankly, Alonso came to a stop on the track and Webber re-entered the track without the Marshall's permission. On the cooling down lap with drivers attention possibly wandering - checking instruments, waving to their mums etc, it is easy to see how someone coming into a blind corner and being confronted with a stationary Alonso and Webber running across the track could have piled into them both.
Simple rules for all.
