Oakland Mayor Libby Schaaf’s warning to illegal immigrants of an incoming raid by agents of U.S. Immigrations and Customs Enforcement in northern California may have led to a number of illegal immigrants with violent and sex-related convictions evading capture and deportation.

Schaaf tweeted out a warning of the raid, alerting targeted individuals to the imminent arrests, and infuriating ICE officials, who say that many more could have been caught if they hadn't been warned.

A spokesperson for ICE gave Fox News examples of some of the unsavory characters who evaded officals during the raid.

One Mexican citizen had convictions for unlawful sexual intercourse with a minor and a conviction for driving under the influence (DUI), and had been deported in 2003.

Another who evaded capture had a conviction for sodomizing a drugged victim in 2012, as well as a DUI from this year -- that Mexican citizen had also been previously deported in 2013.

Another illegal immigrant from Mexico, previously deported in 2014 for a conviction for armed robbery, also evaded capture.

While the individuals dodged authorities, it is also not clear if there was a definitive link between Schaaf’s statement and their disappearance, Fox News reports.
