How did we find out the truth?: On carefully noticing the video, we see a poster and a board printed in Marathi.
We also noticed that the insignia on the policeman's uniform matches with the Maharashtra Police's insignia from the image stock website, Alamy.
Next, by dividing the video into multiple keyframes and performing a reverse image search on them, we came across a video on Facebook which was posted in September 2018.
The video's caption stated the location to be Dhuley, Maharashtra.
We contacted the police involved in the incident: The Quint contacted the Cyber police from Dhule, who confirmed that the video is old.
We then contacted the police station in Chopda who helped us identify the police personnel seen in the video as one 'Shrikant Gangurde'.
Speaking to us, Gangurde said that this video dates back to September 2018.
"This incident took place at Chopda bus stand when I asked a seller, who was Muslim, to move this stall as it was blocking bus' way but it led to a fight. He called him family members named Raheem and Naeem Bagwan, who started threatening me. They created a scene publicly," adds Gangurde.
Conclusion: Clearly, a video of a man shouting at a cop in Maharashtra is being falsely linked with Karnataka.
This same video was viral on social media last year with a false claim that it is from Delhi, you can read our fact-check here.
