At the end of the Nuggets and Heat game in Miami, a fan in a Heat jersey ran on the court while Denver was shooting foul shots and stole the ball. Once he had the ball the fan attempted to make an escape back into the seats.
The police and arena security took it from there.
Hopefully the night in jail and a probable lifetime ban from any NBA games was worth his moment on the court. The fan won't mind the ban given the current play of the Heat.
