There is an Script Include named AttachmentAjax that can be called from a Client Script using GlideAjax to perform several attachment related tasks like: list, delete, rename, etc.

GlideSysAttachment can be used to delete attachment as follows:

var attachment = new GlideSysAttachment();

var agr = attachment.getAllAttachments(<table_name>, <table sys id>);

while(agr.next()) {

        attachment.deleteAttachment(agr.getValue("sys_id"));

}

These script will disable all attachment right. We need only specific attachment to be removed
