How do I delete sub accounts on the PSN?

[JTRaines92]

I am making another account and I am not old enough to be the master account. It says sub accounts have already been made and I only use one, two of them were for my sisters ex boyfriend and his buddy. Is there anyway I can delete them?

you have to log on to them, then delete them by pressing triangle over the username you signed onto.
