Jan. 22 (UPI) -- Immigration and Customs Enforcement has detained four children from the same Minnesota school district this month, including a 5-year-old boy.

Preschooler Liam Ramos was detained in the driveway of his home along with his father, Adrian Alexander Conejo Arias, on Tuesday. The father and son were then transported to a detention center in Texas.

Ramos is a student in the Columbia Heights Public School District in the suburbs of Minneapolis.

The district's superintendent, Zena Stenvik, went to Ramos' home after learning of his detention. She said Ramos and his father had just gotten home when they were detained and their vehicle was still running when she arrived.
