Family and friends of 25-year-old Chad Robertson say the Minneapolis native is paralyzed from the neck down after being shot by Amtrak officials in Chicago.
According to the Chicago Tribune, it happened Wednesday evening.
The post says Amtrak police approached the group "for no apparent reason," told the group to leave, and they complied.
"What happened next is disputed," the post reads but the night apparently ended with Robertson being shot in the back.
Black Lives Matter Chicago says Robertson's family "rushed from Minneapolis to be by his side." The group is also collection donations for the family.
Robertson's sister, Nina Robertson, says her brother has been in and out of consciousness, according to the Associated Press.
The Chicago Police Department told the Tribune that police found drugs but no weapon on the wounded man.
The officers involved are on administrative leave and officials are investigating what happened, FOX 9 says.
There was a rally in Minneapolis Friday afternoon to demand justice and talk about what happened.
