How to delete sent messages from the REST API 1.1


I am working on a notification application that gives subscribed users a direct message in there twitter inbox upon occurrence of some events. The directmessage method in the API works well for me however, I have a problem with the retention of the sent message in the origination account (i.e I still have a copy of the message that was sent to the user in my twitter inbox which i really want to delete for security reasons). Now the challenge is that any time I try to delete the message using a message id, it deletes both the sent copy on my side and the received copy on the user’s side where as i only want to delete the sent copy.

I would appreciate so much if I can get an update on this issue…
