Aldermen are set to consider changes that would strengthen Chicago’s sanctuary city rules. Under Chicago’s ‘Welcoming City’ ordinance, police are mostly barred from holding or detaining suspected undocumented immigrants for federal agents.

Amendments, set to be introduced at the full council meeting tomorrow, would also bar police from making verbal threats of deportation against Chicago residents and their family members.

Immigrant advocates said they feel the changes are necessary after a videotape of a 2013 police raid on a tanning salon showed one officer verbally abusing a Chinese-American woman, and threatening to send her to “wherever the f***” she came from.
