A man was in critical condition in the hospital on Monday after being arrested by several Baltimore police officers in an incident that was at least partly captured on video, police officials said.
Local broadcaster WJZ-TV said family members of the man, who the footage it published showed was black, had identified him as 27-year-old Freddie Gray. He was in an induced coma with spinal injuries, it said.
Use of force by U.S. police, particularly against minorities, has come under increased scrutiny following police killings of black men in Ferguson, Missouri, New York City and North Charleston, South Carolina that have sparked nationwide protests.
The Baltimore incident occurred on Sunday morning.
