The St. Paul City Council Wednesday was expected to settle for $400,000 a case of police brutality filed by a mother and a son over an alleged incident at their home involving St. Paul police, Minnesota Public Radio reported.

The alleged incident occurred on Oct. 28, 2010, at the home of Daniela Hobbs, 48, and her son, Larelle Steward, 28. During the execution of a search warrant for cocaine, the complaint alleged Steward was kicked in the back of head by police -- which resulted in a broken nose -- and had his head covered with a pillow case.

The complaint also alleged that Hobbs, who could not quickly comply with police orders because of a medical condition, had a "flash-bang" grenade shot at her by police, which caused third-degree burns to her lower body, MPR reported.

No cocaine was found in the search, according to MPR.

The Star Tribune reported that the settlement was the largest in a case of police brutality in the city's history.

The city admitted no wrongdoing in the settlement, which also stipulates that Hobbs and Steward don't talk to the media about the case.
