It comes as security issues remain a challenge for both Los Angeles and Paris as they bid for the Games.

Twelve people were wounded in addition to the three deaths after gunfire erupted during a party in a makeshift restaurant in West Adams district on Saturday (October 15).

Two suspects have already been arrested. 

"This marks the latest example of a senseless gun violence epidemic that causes so much pain and sorrow in our city and across the nation," said Mayor Garcetti. 

"We must take action against easy access to firearms and the thoughtless, indiscriminate, murderous use of them.

"We cannot tolerate these tragedies multiplying in communities across America."

Garcetti claimed his city has some of the strictest gun laws in the US when asked about the issue during Rio 2016.

According to a homicide count in the Los Angeles Times, there have been 644 homicides registered in LA County over the last 12 months alone.

They also cite police records claiming overall crime rose by 6.3 per cent across the city in the year ending in July in comparison with the same period over the previous 12 months. 

This is a lower mark than in many other cities, and pales in comparison to 2016 host Rio de Janeiro, but could still be a concern for voting IOC members.

It comes in the same weekend as three men were charged by police following the fatal shooting of Olympic sprinter Tyson Gay’s daughter Trinity at a restaurant car park in Lexington in Kentucky.

"While there is crime in every major city around the world, Los Angeles has seen a decline in crime to historic low levels and, along with the US Government, has the resources to keep the Games safe," a bid spokesperson told insidethegames.

"With the US Secret Service taking lead responsibility for securing the Games, the United States and Los Angeles have proven their ability to host the world's biggest events in a welcoming and safe environment."

Paris are still seeking to allay fears over terrorism following deadly attacks in Nice and in the French capital itself over recent months. 

Bid officials claim that the success of the security operation during the Euro 2016 football tournament shows that they can avoid attacks during an Olympic Games.

It is possible the comments of French President François Hollande last week, when he said that his country has “a problem with Islam” and has too many illegal migrants could further influence the IOC.

Hollande faces a Presidential election next year before the IOC makes its decision on September 13, by which time there will also be a new United States President following a contest next month between Hillary Clinton and Donald Trump.

Budapest are the other contender in a three horse 2024 race following the decision of Rome to suspend their bid last week following a failure to receive City Council support.
