• remove the file and rewrite history from the commit you done with the removed file(this will create new commit hash from the file you commited):

  git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch PATH-TO-YOUR-FILE-WITH-SENSITIVE-DATA' --prune-empty --tag-name-filter cat -- --all

• now force push the repo:

  git push origin --force --all

• now tell your collaborators to rebase.
