Puerto Rico's government says it has raided three more businesses with a combined tax debt of over $500,000, the latest of 132 firms collectively owing $48.9 million that are being targeted in a campaign started last year.

Treasury Secretary Juan Zaragoza announced the raids in a statement Friday night.

He says it is unfair for businesses to collect taxes from people struggling with tax and utility rate hikes and fail to deliver the money to the government.

The U.S. territory's government is grappling with a fiscal crisis that has made it miss multimillion-dollar bond payments three months in a row.

A rescue package recently enacted by Congress creates an oversight board to help Puerto Rico straighten out its finances and protects it against creditor lawsuits through February 2017.
