Community Initiatives for Visiting Immigrants in Confinement is the latest group in recent years to document allegations of abuse at immigration detention centers, based on information obtained from public records requests. It comes as President Donald Trump prepares to expand detention capacity in a drive to deport more people.

The numbers obtained by the group and released Tuesday don’t provide details on individual cases or a full accounting of how the complaints were addressed, but they suggest complaints are common. The department had no immediate comment.
