The Jax Sheriff's Office said they were finding people hiding in the area and urged people to remain calm, as they warned others to stay far away from the Jacksonville Landing.

'We are finding many people hiding in locked areas at The Landing,' they tweeted.

'We ask you to stay calm, stay where you are hiding. SWAT is doing a methodical search inside The Landing.

'We will get to you. Please don't come running out.'


Horrifying livestream audio from the tournament captured the screams of players as the gunfire erupted while two young men were playing in the championship series.

The commentators could be heard going silent as the first gunshots were fired and people began screaming.

The stream then cut out and a message appeared saying 'controller disconnected'.

One of the gamers, Drini Gjoka, revealed his horror after he was shot in the hand and ran for his life.

'The tourney just got shot up. I'm leaving and never coming back. I am literally so lucky. The bullet hit my thumb. Worst day of my life,' he tweeted.

'I will never take anything for granted ever again. Life can be cut short in a second.'

Another witness, Ryan Alemon, told CNN he hid in the bathroom for about 10 minutes before fleeing the bar when he was certain the shooting was over.

'Everyone was running, they were dropping because they were getting shot. I heard yelling, I heard 'Help me, I'm shot',' he said.

Multiple emergency crews were spotted on the scene and authorities said several victims had been transported to hospital.
