A vandal stole a cherry picker on Sunday and used it to tag Brooklyn’s Grand Army Plaza arch with massive graffiti that read, “Bird God.”

Videos and photos from social media show cars driving around the arch in Prospect Park as onlookers watched and cops tried to coax Denis Shelagin down.

The problem is, he couldn’t figure out how to lower the bucket and had to be helped down by the NYPD’s Emergency Services Unit, according to cops.

Shelagin, 36, who lives in Washington state, was arrested and charged with making graffiti, criminal mischief and grand larceny.

It was unclear how the vandal commandeered the crane and raised himself up to mark the arch no one noticing, hours before a menorah-lighting ceremony nearby.

It was not immediately known whose crane it was, and cops were unsure what the tag “Bird God” referred to.
