Several gunshots were heard in Miami's Dolphin Mall early Sunday morning, sources revealed.

Some of the people present in the mall at the time took to Twitter to inform others of what has transpired. Reports suggest that there is an active shooter in the shopping place.

On the other hand, a video also surfaced that allegedly shows the panic-stricken visitors running through the mall amid the sound of firing in the background.

Geo.tv was able to speak to a witness at the scene.

Alejandra Peña, 18, who is a resident of Miami, Florida, explained she "heard people screaming and running" when she, alongside her friends and family, was on the second floor.

"Everyone was running [but] I couldn't see the shooter," Peña recalled to Geo.tv via Twitter's direct messaging service. "I think there were multiple [shooters, but] police backed us away and made us hide by the theatres," she added.

The witness said considering it was 9 PM (local time), there were a lot of visitors and shoppers in the mall. However, she was unable to comment on whether there were any casualties.

"There is still a large police presence inside and outside of the mall. if you can, avoid the area," Twitter user @FirstNewsHQ tweeted.
