Few details of the arrest were available, but Antioch police Sgt. Tony Morefield said the suspect was arrested in the 5300 block of Rockrose Way near Hillcrest Avenue. Antioch police Chief Allan Cantando posted on the department's Facebook page that it happened just before 6 a.m.
Details about the home-invasion robbery were not released. Pleasanton police Lt. Jeff Bretzing cited the pending investigation and declined comment when contacted on Thursday.
Neither agency commented when asked why SWAT teams were involved.
"What I can tell you is that this was a very high-risk subject," Morefield said. "And this is a pretty serious case."
