If $\alpha$ is irrational, you can find such a sequence (the sequence of convergent's numerators and denominators, for example). So the proof you are looking for does exist :p

comment Does “locally connected and path-connected” imply locally path-connected?
Next time, you could use austinmohr.com/home/?page_id=146 It's a searchable database of the counterexamples that you can find in the book. Unafortunately, this time, your counterexample was not known...
