Help Manually tear the cloth

[bluedrag0n]

Hi, 

I need to manually tear the cloth based on the particle I selected. I have the particleindex of the selected particle and need to tear that particle from the particle above it, or remove the distance constraint. Is there a way to do it without using physics/force? I can get the cloth's distance constraints and traverse through the batches but I can't figure out how to find the correct constraint.

Thanks
