President Donald Trump was unfortunately proved right once again on Tuesday after an outbreak of violence and anger broke out overnight in the predominantly migrant town of Stockholm in Sweden.

Swedish police are investigating a riot that erupted in a housing development after officers arrested a suspect on drug charges.

Masked men set cars ablaze, looted local small businesses, and threw rocks at cops, injuring one police officer, Swedish officials said.

One police officer was even forced to open fire on during the chaos.

"This kind of situation doesn't happen that often but it is always regrettable when it happens," a police spokesman said.

On Saturday, President Trump was heavily criticized for warning Americans of the dangers of Sweden's open border policy which is allowing record numbers of foreign migrants into the country.

“Sweden. They took in large numbers [of refugees],” Trump said at a Florida rally. “They’re having problems like they never thought possible.”

The Swedish government responded by saying on their Twitter, “Hey Don, this is @Sweden speaking! It’s nice of you to care, really, but don’t fall for the hype. Facts: We’re OK!”

In March of 2016, 60 Minutes Australia released controversial footage of their own camera crew being violently attacked by a group of Arab men while filming in Sweden.
