Who's the man seen wearing the ISIS logo in Houston?

HOUSTON (KTRK) -- A post that's been making the rounds on popular sites such as Facebook and Reddit have some concerned about ISIS activity in Houston.

Eyewitness News has been working to get some real answers or responses about the picture that's going around, but it's more difficult than you may think. The picture shows a man supposedly wearing an ISIS logo at a Houston restaurant.

We contacted Houston police, who referred us to the FBI. The FBI told us they know about this story, but they were not aware of any arrests being made and were also unaware of any specific credible threats within the Houston territory.

So for now, a lot about the picture remains unknown, but it's definitely got a lot of people talking.

We'll keep working to get you answers.
