Police say they've arrested a man dressed as a tree for blocking traffic in Maine.

They say the man didn't respond to officers when they warned him against obstructing traffic in a busy intersection in downtown Portland.

NBC affiliate WCSH-TV posted video of the man being arrested after he blocked traffic again.

A friend of the man, identified by authorities as 30-year-old Asher Woodworth, says he was trying to study the city's traffic patterns.

Woodworth, who was charged with obstructing a public way, appeared to be dressed as a pine tree or other type of evergreen.

Portland police hasn't provided additional details.
