How to remove an element from plydata['vertex']

[JACMoutinho]

I was wondering if you could me with something, not really an issue:

I want to delete certain values from a point cloud using plyfile, like the example i have bellow where i want to delete the coordinate with index 567890 so that i can later produce a new ply file without that point.

How would ago about that?

Thank you for your help and have a wonderful weekend.
