The Avengers have a new problem - Iron Man's suit has gone missing. 

Los Angeles police said the gold and red suit worn by Robert Downey Jr. in the original 2008 superhero smash hit was reported missing on Tuesday from a storage facility.

Downey Jr. has played the role of billionaire Tony Stark since 2008. He's reprised the role for two more Iron Man films since and The Avengers franchise.

Officer Christopher No told AFP the owners of the warehouse believe the iconic costume vanished between February and April 25 from the prop storage warehouse in Pacoima, located north of downtown Los Angeles.

No said the "unusual" theft was considered high priority, and detectives so far had no leads in the case.

The suit is valued at $US325,000 according to the New York Post.
