Alex Pretti broke rib in confrontation with federal agents a week before death, sources say

Federal immigration officers have been collecting personal information about protesters and agitators in Minneapolis, sources told CNN – and had documented details about Alex Pretti before he was shot to death on Saturday.

It is unclear how Pretti first came to the attention of federal authorities, but sources told CNN that about a week before his death, he suffered a broken rib when a group of federal officers tackled him while he was protesting their attempt to detain other individuals.
