Four men face assault charges in connection with the beating of an Alabama high school student who had posted pro-police comments online, police confirmed Wednesday.

The men, all former Sylacauga High School students, were arrested Tuesday after the Sept. 30 attack against 17-year-old Brian Ogle. Police have said the attack may have been racially motivated. All four suspects are black and the victim is white, Fox News reports.

Ogle's mother, Brandi Allen, says her son responded to students wearing Black Lives Matter T-shirts at his school with "Blue lives matter," a defense of police officers. Officers found him bleeding on the ground after a homecoming football game. He was hospitalized with serious head injuries.

Twenty-year-old Quartez Walker and 19-year-old Bobby Brown were arrested at Stillman College. Eighteen-year-old La Noah Ealy, Jr. was arrested at Auburn University in Montgomery. Twenty-year-old Daveon Nix was arrested in Sylacauga. Nix is the son of Sylacauga District 2 City Councilwoman-elect Tiffany Nix, The Daily Home reported.
