ICE is joining D.C. police patrols. Moped drivers are getting detained.

A growing number of delivery drivers, most of them from Central or South America, are being detained by federal agents on D.C. streets and put into immigration detention in one of the most visible and high-profile effects of President Donald Trump federalizing the D.C. police force.

Many of these cases are the result of a new practice: Immigration and Customs Enforcement agents are accompanying D.C. police officers on moped traffic stops to determine the immigration status of those delivery drivers, and then detain and deport them if they are in the United States illegally, according to three police officers who spoke on the condition of anonymity because they were not authorized to speak publicly.
