NEW YORK (CBSNewYork) — The NYPD was on the hunt Monday afternoon for a man accused of attacking a security guard at the Metropolitan Museum of Art after complaining about a crooked painting.

The 46-year-old guard told the man not to touch the artwork and advised him to inform the staff at the information desk, police said.

As the guard turned to walk away, the man smashed a glass bottle on the back of his head and shouted, “Do your job!” according to police.

“Oh, really?” said museum visitor Jonah Diaz. “Wow, that’s ridiculous.”

“It’s very sad and unfortunate,” said museum visitor Carrie Pozum. “I mean, this should just be a safe place to go and enjoy the art.”

The suspect apparently cut his hand on the broken bottle, leaving a trail of blood through two galleries. Police followed the trail out the building, but were unable to find the suspect.
