Basically the fire department hates him cause "your going to take our jobs" when a giant firewall was around the city and moving inward.

Police chased him all over the place in a city wide manhunt... becoming "public enemy number one", they blamed him for the fire wall is what I'm thinking.

He had a new form that gave him a bit of super speed so he kept getting away and he's melted some streets signs, BY ACCIDENT!
