A security guard at the Carnegie Museum of Art told police he “didn’t like” the $1.2 million painting he allegedly destroyed.

The suspect — Timur Serebrykov, 27, of Pittsburgh — is being held in the Allegheny County Jail on a felony charge of institutional vandalism, police said.

According to a police affidavit, surveillance video from May 16 shows Serebrykov defacing Vija Celmins’ “Night Sky #12” at the museum on Forbes Avenue.

The affidavit said there was an “obvious large vertical gouge” in the middle of the piece.”I did it with a key… I didn’t like the painting… I’m sorry,” Serebrykov told Detective Daniel Sullivan, according to the affidavit.

Very strange.
