Chilling image of downtown LA posted online by terrorist group

Los Angeles police are looking into a chilling photo posted to the internet on Friday by an ISIS-supporting group showing a photoshopped explosion to a high-rise in downtown Los Angeles.

The disturbing, photoshopped image has been circulating on dozens of websites and media publications and shows a person in uniform with their face hidden and holding what appears to be the ISIS flag posing in front of the downtown skyline at night with a blast at the top of the Aon Center.

LAPD tweeted that at this time they have not been able to find a credible threat to the city's buildings in connection with a social media post. However, law enforcement officials continue to work with federal agencies to "coordinate any information that will lead to the source of the post."

FOX 11 reached out to Aon, who provided the following statement:

"Aon's building security has confirmed with the Department of Homeland Security that this is a non-credible threat."

Authorities urge residents and visitors to be on alert for anything suspicious and "if you see something, say something." Report any suspicious activity on or 1-877-284-7328.
