An immigration lawyer said she fractured her foot after being pushed to the ground by an Immigration and Customs Enforcement officer as she followed her client, a 3-year-old boy, into an ICE building in Kansas City, Mo.

The lawyer, Andrea Martinez, said that she and a colleague were trying to accompany the child, Noah Bautista-Mayorga, into the ICE office around 3 a.m. Tuesday. Noah’s mother, Kenia Bautista-Mayorga, had been detained since May.

The family had entered the country illegally in February 2016 and was to be deported to Honduras on Tuesday morning.

Ms. Martinez said that she and the other lawyer were pushed forcefully by the ICE officer as he tried to block her from entering the building. The encounter was captured on a widely circulated video, which shows a brief scuffle between the two lawyers and an ICE officer, with Ms. Martinez tumbling to the ground after she approaches the door to the building.
