This is not the headline NBA Clippers owner Steve Ballmer envisioned when he sunk $2 billion into building a brand new state-of-the-art arena.

Cops are on the lookout for the 2 male teenagers who broke into the Intuit Dome — which is still under construction in Inglewood, CA — and ran around the place like they owned it … shooting hoops, climbing on scaffolding and spraying fire extinguishers.

They pulled off the brazen caper last week, recording the whole thing … and proudly posted it on TikTok, which is likely what will get them busted.

The video shows them climbing a construction crew’s ladder at night to gain entry, and then strolling around the empty hallways and bleachers. When they found an unfinished basketball court, they decided to take a few shots.

They did all of this while showing their faces, and, as a result, Inglewood Mayor B has since identified the pair and their parents. Butts told ABC 7, “It will be very clear to these young men — and to people who are TikTok followers — that you have a moment of TikTok greatness followed by a little bit of misery. And so we don’t play around with these things.”

It’s unclear if cops have made contact with the suspects yet, or what their punishment might be.

The Clippers started work on the dome in September 2021, and it’s set to open in August … and in addition to being the Clippers’ new home court, it will be a concert venue. In fact, Usher is slated to be the first performer this summer.
