(CNN) None of the 42 migrants arrested in Sunday's clash at the US-Mexico border will be criminally charged.

Two of the arrested migrants had been referred to the Department of Justice for prosecution, but US Customs and Border Patrol later asked the DOJ to drop the charges, an administration official told CNN.

A "vast majority" of the 42 arrested on Sunday were adult males, according to the Department of Homeland Security. Tyler Houlton, a DHS spokesman, told reporters on Tuesday that he believes seven females, "a few children" and 27 adult males were arrested.

CNN does not know the current status of those that were arrested.
