A man was arrested Saturday for allegedly threatening to ignite an explosion at the Laguna Niguel/Mission Viejo Metrolink station, authorities said.
The suspect was taken into custody at about 1:30 p.m., according to spokeswoman Carrie Braun of the Orange County Sheriff's Department.
While at the station at 28200 Forbes Road, the suspect called authorities at about 8:30 a.m. to say that he was planning to do some "intentional harm'' at the location, prompting a response by deputies, a SWAT team, a bomb squad and the Orange County Fire Authority, Braun said.
