If you see a tweet in a hashtag stream that you want to delete, there are a few simple steps you need to follow to remove it. Unfortunately, you cannot delete someone else's tweet; it must be a tweet from an account to which you have access.
Delete a Tweet From a Computer
To delete your unwanted tweet, sign in to the Twitter account from which the tweet was sent. Navigate to your profile page, and find the tweet that you would like to remove. Hover over the tweet with your mouse. The "Delete" option will appear. Click "Delete."
Delete a Tweet From a Smartphone or Tablet
Launch the Twitter app on your mobile device or tablet, and navigate to your profile. Sometimes, this is displayed as a "Me" button. A list of your tweets will appear. Locate the tweet you want to remove, and tap on it. Tap the trash icon, and confirm that you want to delete the tweet.
