A shooter who killed four and wounded multiple others after opening fire at Madden NFL video game tournament in America was reportedly a gamer who lost $5000 in the competition.

The Los Angeles Times reported the gunman appeared to target several victims in Jacksonville, Florida, before turning the weapon on himself.

US police were unable to comment on the reports from US media.

The horrifying incident took place at a gaming venue called Good Luck Have Fun inside Chicago Pizza in Jacksonville Landing during a live Twitch streaming of the event.

Police said the deceased suspect was a white male and that they are no longer looking for any more suspects.


In footage streamed online through Twitch nine shots can be heard before there are several screams and shouts.

One Twitter user, Drini Gjoka, said he was in the tournament and was shot in the thumb.

"Worst day of my life," Gjoka wrote on Twitter. "I will never take anything for granted ever again. Life can be cut short in a second."

The Florida shooting took place amid a debate about U.S. gun laws that were already under scrutiny after the massacre of 17 people at a high school in Parkland, Florida in Feburary.


The sheriff's office said many people were transported to hospital, and its deputies were finding many people hiding in locked areas at The Landing.

"We ask you to stay calm, stay where you are hiding. SWAT is doing a methodical search," it said on Twitter. "We will get to you. Please don't come running out."

Staff at Jacksonville's UF hospital are also reporting that they are treating six people - five are stable and one is in a serious condition.

"This is a horrible situation, and our deepest sympathies go out to all involved," the company said on Twitter.
