Alarming comments from Baltimore's mayor about human trafficking were not based on a specific incident, local and federal authorities said.

During an interview Monday with 11 News, Mayor Jack Young made some comments asking people to avoid parking near white vans.

"We're getting reports of somebody in a white van trying to snatch up young girls for human trafficking and for selling body parts, I'm told. So we have to really be careful because there's so much evil going on, not just in the city of Baltimore but around the country," Young said. "Don't park near a white van. Make sure that you look at your surroundings, and make sure you keep your cellphone in case somebody tries to abduct you and call 911 right away."

Federal and local law enforcement officials said human trafficking is a real concern that affects millions of families worldwide every year, which is why Young's comments were taken seriously. WBAL-TV 11 News was interviewing the mayor on a different topic when he, on his own, brought up the alleged attacks involving white vans.

On Monday night, 11 News asked Baltimore City police whether they have any reports of abductions involving white vans, and said they didn't.

On Tuesday, 11 News asked the FBI whether they have any reports of abductions in Baltimore involving white vans, and they also said they had not received any reports.

So where did the mayor get the idea that this is happening in Baltimore? In the interview with 11 News, the mayor pointed to posts on Facebook. Both city police and the FBI told 11 News that they are aware of the social media posts, but they have no reports of such crimes actually happening.

A City Hall representative told 11 News that the mayor was making a general comment and was not talking about a specific incident.

WBAL-TV 11 News requested a follow-up interview with the mayor Tuesday morning to give him an opportunity to clarify his comments. So far, there has been no response to 11 News' request.
