How to Remove a Friend From LinkedIn
If you have a LinkedIn connection that you've decided you'd rather not be connected to, you can delete this person as a friend so you're no longer connected on the network. LinkedIn, a social networking site for career-minded individuals, allows you to friend and defriend or connect to and de-connect with other users as you please. You can learn how to remove a friend on the LinkedIn social network by following a few steps.
