PORTLAND, Maine (NEWS CENTER) -- Did you receive an angry rental housing violation letter from the City of Portland? You may have been an unintended target.

City officials offered an apology Wednesday on Twitter, saying they made a mistake with their data and some letters may have been received in error.

"Our intent was to reach the property owners who have previously been unresponsive to our requests for registration," they wrote. "We are working hard to register all units in Portland so we can achieve a safer housing stock."
