DALLAS — A man who broke into the Dallas Museum of Art on Wednesday night caused roughly $5.153 million in damage, destroying property including three ancient Greek objects before he was arrested, Dallas police said.

Brian Hernandez, 21, approached the museum’s glass entrance doors with a metal chair at about 9:40 p.m. Central time, and began destroying objects once inside, police said.

Hernandez broke into a glass display case and shattered a sixth-century B.C. Greek amphora — a type of ceramic vase — and a Greek pot from 450 B.C. The pieces together were valued at approximately $5 million, police said, based on information from the DMA’s security and operations director, Kenneth Bennett. They noted that estimates could change after a final assessment by a curator and the museum’s insurers.

He also is accused of destroying a 550-530 B.C. bowl that was valued at $100,000. Police said he broke into a display case, picked up a ceramic Caddo effigy bottle depicting an alligator gar and slammed it to the ground, shattering it. The piece was valued at $10,000.

“This was an isolated incident perpetrated by one individual acting alone, whose intent was not theft of art or any objects on view,” museum officials said in a statement Thursday. “However, some works of art were damaged, and we are still in the process of assessing the extent of the damages.”

The museum was open to the public Thursday, including its “Cartier and Islamic Art”exhibition. Some permanent collection galleries will be closed for the ongoing investigation.

The shattered objects are among more than 24,000 works in the DMA’s cross-cultural collection, which spans 5,000 years. Even with their price tags, they’re hardly the costliest items the museum has housed. For eight months in 2012, a painting by Leonardo da Vinci now considered the world’s most valuable artwork reclined on an easel in a storeroom in the building. It sold at auction to the Saudi crown prince for a record $450.3 million in 2017.

Hernandez was read his rights and confessed to officers, police said. He was charged with criminal mischief of more than or equal to $300,000. Bail has not been determined.

The museum noted that Hernandez was not armed.

A DMA security guard found Hernandez on the museum’s concourse after a motion sensor went off and apprehended him before calling police. Police said Hernandez also called 911 on himself from inside the museum. Police responded at about 10:10 p.m.

Hernandez is being held in the Dallas County Jail, Dallas police said Thursday.

The guard told police that Hernandez said “he got mad at his girl so he broke in and started destroying property,” police said.

Police officers said Bennett, the DMA security and operations director, showed them video of the suspect damaging and destroying museum property. In addition to the artwork, Hernandez is accused of causing tens of thousands of dollars in damage to other property including display cases, furniture, a computer and phones.

“While we are devastated by this incident, we are grateful that no one was harmed. The safety of our staff and visitors, along with the care and protection of the art in our stewardship, are our utmost priorities,” the museum said.

DMA board member Mary McDermott Cook, whose late parents donated or made available to the museum thousands of pieces of art, got a firsthand account of the vandalism Thursday morning from museum director Agustin Arteaga. The call “made me sick to my stomach,” Cook said.

“I feel like everything has gone nuts, and this is one thing that went nuts,” she said. “But what I also said is, ‘Let’s face it. It’s just things. No person was hurt. And we have the technology and the expertise to put broken things back together.’ And thank God for that.”
