Gas Fire

I was at the gas station the other day pumping my gas. There was a man at the pump next to me also pumping his gas and the next thing i knew his hand and arm caught on fire. I took off running but stayed within view curios to see the outcome. Well the police and fire trucks came. he immediately got arrested.

I came back confused. I asked the cashier what happened?

She said they got him with an illegal fire arm.
