Three Black men were arrested for allegedly assaulting a White passenger on the St. Louis MetroLink train after the latter refused to talk about the Michael Brown case, according to media reports.

David Autry was riding the train on the way home when a man approached him talking about the Michael Brown case, according to the New York Daily News.

When asked, Autry said he had no opinion on the issue, that man began striking him, and another man joined in, the Daily News reported.

“I think it was disgusting that no one (helped),” Autry told CBS affiliate KMOV.  “People were sort of laughing and smiling about it. No one offered to help and no one attempted to call 911.”

The St. Louis Post-Dispatch reported that three men were arrested March 30 in connection with the attack, among them a 21-year-old, a 15-year-old, and another individual who was cooperating with the investigation.

Autry has started a GoFundMe page to help raise $5,000 for lawyer fees and a motorcycle so he can avoid taking the train. Autry plans on donating money from his funds to other victims of crimes in the St. Louis area.
