Armed robbers seize boy in California

Federal and local authorities kept up their search for a 3-year-old Californian boy snatched from his home by armed robbers who threatened to kill him.

The gunmen burst through the family's front door on Monday and tied up 3-year-old Briant Rodriguez, four of his siblings and their mother, Maria Rosalina Millan, then ransacked the house, stealing money and other property, the San Bernardino County Sheriff's Department said.

After about 20 minutes, the men left with Briant, ordering his mother and the other children not to call police.

The motive for the abduction was unknown.

"There has been no demand for ransom, there has been no contact with the family," sheriff's spokeswoman Jodi Miller said.
