1 dead and multiple injured following crowd surge after rapper GloRilla concert in upstate New York, police say. The city's mayor vows 'to hold people accountable.'

• One woman died and several others were injured after a GloRilla concert in Rochester on Sunday, police said.
• Police said the injuries were a result of "people being trampled."
• GloRilla sent her condolences in a tweet on Monday. 

One person died and multiple people were wounded following a stampede at a concert in Rochester, New York on Sunday night, police said. 

At a Monday morning press conference, Rochester police said that the crowd surge at the end of the event at Main Street Armory where Grammy-nominated rapper GloRilla and Finesse2tymes performed was triggered by the false panic of a shooting, as the concertgoers were leaving the venue shortly after 11 p.m.

The venue did not immediately respond to Insider's request for comment on Monday.

One of the women, identified as a 33-year-old, died and the two others were reported to be in critical condition, authorities said. Seven other victims were also hospitalized for non-life-threatening injuries, police added.

"Preliminary reports from people at the scene indicate that these injuries were caused from people being trampled," Police Chief David Smith said at the press conference. "We do not have any evidence of gunshots being fired or of anyone being shot or stabbed at the scene."

Smith said the incident this under investigation and that officials are looking into "reports of potential causes including crowd size, shots fired, pepper spray and other contributing factors." He noted that investigators are interviewing witnesses who were in attendance. 

GloRilla offered her condolences in a tweet Monday morning. 

"I'm just now hearing about what happened wtf," she said. "Praying everybody is ok."

One concertgoer told WHEC that the venue was "deathly packed." Police said when officers entered the building, they discovered three injured women, and first responders "provided life-saving measures" at the scene. The victims were transported to a local hospital. 

Rochester Mayor Malik Evans called the incident a "tragedy of epic proportions," adding that "we are going to hold people accountable for what happened last night, period."

Evans asked the public for any photos or videos taken during the concert to help with the investigation. 

"We are nowhere near completing this investigation," he said.
