A bomb threat at the Santa Monica Pier in California is being investigated by police who have evacuated the popular tourist destination. The timing of such a scare on the 16th anniversary of the September 11 terrorist attacks may heighten security concerns.

The SMPD has advised people to avoid the Santa Monica Pier until further notice due to “police activity.”

Police were first made aware of a possible bomb threat from notifications by the Hawthorne Police Department and the Culver City Police Department. No link has been found to any particular caller, according to the SMPD.

A perimeter search of the pier was conducted, and a suspicious vehicle prompted the evacuation. Local FBI officers have been assisting in the investigation.
