Donald Trump's Star Vandal Has Been Arrested

The guy who destroyed Donald Trump's Walk of Fame star got busted by cops Thursday morning.

LAPD tracked down James Otis in West Hollywood as he was leaving a home, and took him into custody. We're told he was cooperative as officers arrested him for felony vandalism.

Otis was planning to hold a news conference in a few hours ... then turn himself in to cops, but LAPD clearly wasn't down for his dog and pony show.

As we reported ... Otis took a pickax to Trump's star early Wednesday. He came on "TMZ Live" a few hours later to confess and explain why he had it out for the GOP candidate.
