MANHATTAN, N.Y. — The Museum of Modern Art will remain closed Monday, two days after a pair of employees were violently attacked by a man who was allegedly denied entrance. The museum is expected to reopen on Tuesday.

Authorities have announced they are searching for a 60-year-old man named Gary Cabana in connection to the incident, which happened around 4:15 p.m. Saturday, but no arrests have been made. The incident began when the suspect attempted to gain entrance to the museum with an expired membership, according to NYPD officials. 

The man allegedly became enraged and video from the scene showed him jump over the counter to attack the museum workers.

“They were just doing their job. I mean I was working here three months ago and I thought it was a safe place to work,” said Lucia Laconte, visiting from Argentina.

One worker was stabbed multiple times, while the other suffered a wound to the left collar bone. Both were taken to Bellevue Hospital and are expected to survive, according to police.

NYPD Deputy Commissioner of Intelligence and Counterterrorism John Miller said the incident was "spontaneous" and "rapidly unfolded" too quickly for security to stop the man. One security guard on the other side of the counter began throwing objects at the suspect in attempt to distract the attacker from the employees. 

"What they may look at is having more security at the location where money is received for tickets," said Robert McCrie, a professor of security management at John Jay College of Criminal Justice. "They may have a counter that is built slightly higher and more of a distance between the customer and the museum personnel."

MoMA is one of the institutions throughout the city using Evolv Technology, a security device that looks like a metal detector, but doesn't require patrons to stop or unpack their bags. Instead, it uses artificial intelligence to identify all the items it detects. 

In the surveillance footage from the incident, it appears the suspect jumped over the front desk before he would have had to walk through the security screening station. McCrie said a metal detector at the entrance could have spotted the knife before he reached the employees behind the counter. The museum has yet to say how or if it will update its security protocols.

The museum was evacuated following the incident and has been closed to the public since.

The NYPD said Cabana has been reported for "disorderly conduct" at the museum before and he is known to the staff. Police said he is not a previous employee.

Authorities note that the investigation remains active and ongoing.
