Step 1. Sign in to your Facebook profile. In the "Search" box, start the name of the person to introduce you want to remove as a friend. When his name appears on the option list below this box, click it to go to his profile.
Step 2. Scroll down on your friend's profile, while keeping an eye roll to the left column (where his profile picture is located). Under the profile photo will give you a list of at least 10 of his friends. A little further down, you will see a list of options.
Step 3. Click the "Unfriend" link on the list of options. As a result, Facebook asks you if you are sure you want to remove this person from your friends. If you are, click on "Remove from friends". If not, click "Cancel".
