Steve-O -- Charged in Fireworks Stunt

EXCLUSIVE

Steve-O's human King Kong stunt atop a Hollywood crane earlier this month could land him in jail -- the Jackass star's been hit with 5 misdemeanors.

The L.A. City Attorney charged Steve for creating a false emergency, use of unregistered fireworks, storing and possession of fireworks without permit, and trespassing. 

Cops responded to calls that a jumper had climbed a construction site crane over Sunset Boulevard on Aug. 9 -- but eventually realized it was Steve-O protesting SeaWorld with an over-the-top stunt.

If he's convicted of all charges he faces up to 4 and a half years in jail.
