Hundreds of police officers in Puerto Rico are taking to the streets to demand higher salaries and the payment of back wages.

Police accuse the government of not honoring several laws that among other things would give them an additional $200 a month. The officers plan to file a complaint Tuesday with an appeals court.

Puerto Rico has the second largest police force of any U.S. jurisdiction, with some 17,000 officers. The department has come under fire due to a record number of homicides last year.

Federal prosecutors also have accused the department of corruption and civil rights violations, and the American Civil Liberties Union has also filed two lawsuits related to those complaints.
