According to the Redondo Beach Police Department, officers responded to claims of a hostage situation involving possible explosives near the pier at approximately 9:36 a.m.
When officers arrived, they established a perimeter around the pier, evacuated visitors and had residents shelter in place.
Officers conducted an extensive search and determined there was no active threat to the pier, nearby residents or the surrounding community.
"Out of an abundance of caution, explosive detection K-9s were deployed to assist in clearing the affected areas. At approximately 1:34 p.m., the Redondo Beach Police Department determined there was no danger to the public, and the Redondo Beach Pier was reopened," the police department wrote in a press release.
The investigation into the incident is ongoing, but police believe it is an isolated event and there is no ongoing threat to the public. The FBI responded to help assist Redondo police with the investigation.
Meanwhile, the police activity briefly delayed Sunday's opening time for the BeachLife Festival, a three-day festival that kicked off on Friday and featured musical guests like Duran Duran, The Offspring and James Taylor.
"Per the direction of local safety officials, we have been given the go-ahead to safely open doors momentarily," read a statement posted on the festival's Instagram account.
The term "swatting" refers to fake calls made to 911 indicating a serious emergency, but when officers respond to the scene, no real threat is found.
Anyone with information is urged to contact the Redondo Beach Police Department Detective Bureau at (310) 379-2477, extension 3507.
