Chase rules

[Banana4Life]

So I was chasing someone, and they kept trying to push me into a wall. Let's say there is a straight, and on the grass next to the straight there is a wall not parallel to the straight, so it goes across the grass so you can't go along the grass if that makes sense. If I'm on the side closest to the grass and the suspect is on the other side of me and they turn into me making me hit the wall on purpose (was slowing down to wait for me to do it), is it allowed? I had to stop chase after a few times he/she tried/did the same thing, so was wondering if allowed or not
