A person was arrested at John F. Kennedy International Airport in New York City overnight related to the investigation into last month’s bombing outside a fertility clinic in Palm Springs, California, a U.S. official familiar with the investigation told CBS News.

The individual may have provided material support for the bombing, but it isn’t clear if they knew about the bombing. The bomber, identified by officials as 25-year-old Guy Bartkus, died in the blast. Four other people were injured in the explosion.Police in Palm Springs said the bomber backed his Ford Fusion into a parking spot outside the clinic and the powerful explosion left a crater on the morning of May 17. The explosion could be felt more than a mile away from the blast zone, the FBI said.
