Protests have erupted across the US after the Immigration and Customs Enforcement (ICE) agency swept across several US cities, detaining undocumented migrants.
Early Friday's raids came quickly after President Donald Trump signed three executive orders on Thursday reportedly aimed at crime reduction.
Los Angeles, Austin and Phoenix have all seen demonstrations.
In Austin, at least five undocumented residents have been detained.
Cristina Parker, the immigration programmes director at Austin-based Grassroots Leadership, which organises against deportations and mass incarceration, informed Al Jazeera there may be more.
"Everyone is scrambling to get information. There are unconfirmed reports of detentions across the city. Those who are most affected by these actions are the hardest to get in contact with, currently," Parker said.
Austin has been the epicentre of the national battle over so-called sanctuary cities, an unofficial designation of cities that generally offer safety to undocumented migrants and often do not use municipal funds or resources to advance the enforcement of federal immigration laws.
According to local reports, the ICE detained each of the five in separate, targeted raids.
