NEW YORK (AP) — The FBI has made an arrest in New York in connection with an explosion of a Palm Springs, California fertility clinic, three law enforcement officials familiar with the matter said Wednesday. Federal prosecutors are expected to release details about the case at a news conference in Los Angeles.

The FBI have arrested a man at New York's John F Kennedy airport on Tuesday night in connection with last month's car bombing outside a fertility clinic in Palm Springs, California. Authorities said Daniel Park, 32, from Kent, Washington, sent 180 pounds of ammonium nitrate - an ingredient used in homemade bombs - to Guy Edward Bartkus.

Federal authorities announced Wednesday the arrest of a Washington state man they say provided chemicals to make explosives used to bomb a California fertility clinic in May.
