Part 107 pilot reported flying a UAS in an active TFR. It was during the post-flight the UAS pilot learned of the TFR.

Narrative

I accidentally flew in a TFR. There was a fire yesterday evening just outside of ZZZ. I sometimes do free video and pictures; of news events; for a local news organization. I checked sky vector app on my phone to see if there's any restrictions. It did not say that there was. I also checked Flightradar24 to see if there were any aircraft in the area. There was not. I was south of the road and flew for about 10 minutes. As I got done and was leaving a Public Official that I know pulled up and said that I shouldn't be flying and that the Public Information Officer wanted to talk to me. When I got over to the other side where the Public Information Officer was he informed me of the TFR. And search-and-rescue we fly in and deal with TFRs all the time. So I know the importance of them. The Information Officer name was Person A. He stated that he would probably not report it; since there were no aircraft in the area. But I want to make sure that I'm doing everything by the book. I apologize to him and his guys for any issues that it may have caused. I do fly in conjunction with law enforcement and other emergency service agencies so am very well aware of what needs to happen and thought my bases were covered when I checked the apps.
