British Police Arrest Four For Racially Abusing England Soccer Players, Vow To Find More

British police say they've arrested 4 people for racially abusing Black England soccer players following the team's Euro 2020 loss ... and officials say the hunt for more is nowhere near over.

Jadon Sancho, Marcus Rashford and Bukayo Saka -- who are all Black -- were ambushed by racial slurs on social media after they each missed key kicks in England's shootout loss to Italy on Sunday.

The comments and remarks were vile -- many featured the n-word and others contained violent threats -- and it got so bad, UK police launched an investigation into it all.

And, in an update on the probe Thursday, British officials said they've arrested four in connection with the online attacks ... adding more arrests could be coming soon.

"We are working very closely with social media platforms, who are providing data we need to progress enquiries," British police official Mark Roberts told reporters.

"If we identify that you are behind this crime, we will track you down and you will face the serious consequences of your shameful actions."

Of course, in England, it's illegal to make racist statements or threats, as there's no First Amendment protection.
