How to obtain attachment name and attachment type using IUpdateTableEventInfo?

I have an Event Driven PX that requires to take some action when an attachment is removed from the attachment tab for a Manufacturer's Part Number. Using IUpdateTableEventInfo, I can determine when something is removed but here is what I need help with.

1) when an attachment is removed, I need to retrieve the name "Attachment Type" value to determine what action to take. I can can't figure out how to retrieve that value from the records that is removed.

2) Similarly, I need to retrieve the file name of the record removed.

Any help will be greatly appreciated.

Thank you.
