Gunshots rang out at Del Mar Fairgrounds in Del Mar, California on Sunday evening, as the races were wrapping up for the day and crowds were starting to show up for an Ice Cube concert. The suspected shooter appears to have been the only one hurt in the dramatic event, as police responded with force to the shots fired.

You can watch police subdue the suspected shooter here. An officer wearing a sheriff’s uniform shoots what appears to be a taser at a man in a black shirt and black pants. You can hear four pops and then the man falls to the ground and begins rolling around.

The crowd yells “bullsh*t!” while another police officer yells “get back!” and pushes one man out of his way.

It wasn’t immediately clear what condition the suspected shooter was in. Some witnesses believed that police had also shot him with a gun, after the taser failed to subdue him. News reports said he had been rushed to a nearby hospital.

The Gunfire Was Reported Live and On-Air By a Racetrack Announcer

The gunfire caught everyone off-guard and created panic and confusion at Del Mar.

The announcer — in the middle of giving a moment-by-moment description of the horse race — announced the gunfire live and on air. You can hear that in this clip, here.

As the horses are mid-race, the announcer suddenly yells, “there’s gunfire at the track. There’s gunfire at the track.”

A sudden thumping noise can be heard, although it’s not clear whether that’s the sound of something falling over or the sound of bullets.

A Man Took Out His Gun and Opened Fire In the Fairground — And Some Witnesses Said They Believe Police Killed Him While Trying to Subdue Him

Initial reports on social media were conflicting. There were some reports that a police officer had been shot by a man who suddenly pulled out a gun and opened fire. People were wondering whether a jockey had been shot.

But witnesses later told media that in fact, the suspect had taken out a gun and fired it three times in the air. Police officers rushed to the scene and tased him; he fell to the ground. You can see video of the police subduing the man here.

Some witnesses reported that police had used a gun on him when the taser did not work, but it was not immediately clear whether that was accurate. Some witnesses believed that the suspect had died.

You can see video of the police working to resuscitate him here:

The Gunshots Caused Fear and Confusion in the Crowd and On the Racetrack, as One Spooked Horse Threw His Jockey Off

Police responded very quickly, subduing the shooter almost immediately. It is not yet clear what his condition is.
