SACRAMENTO, Calif. -- An Amber Alert was sent out Wednesday afternoon for a 3-year-old boy, the Sacramento County Sheriff's Department said.

His father abducted the boy, officials said.

The child, Alexsandr Olteanu, is described as white, with brown hair, brown eyes, about 3 feet tall and 35 pounds. He was last seen wearing a yellow T-shirt and underwear.

The suspect, David Olteanu, 28, is described as a white adult, about 5 feet 6 inches tall, with brown hair and green eyes. He was last seen wearing a white T-shirt and blue jeans.

Olteanu's car is a 2007 dark blue Chrysler 300 with a California license plate No. 6DBR388.

The suspect may have several firearms in the vehicle, including an assault rifle, Sgt. Tim Curran said. He should be considered armed and dangerous.

A 28-year-old woman said she was sexually assaulted and bound by the suspect, her estranged husband. She said he told her he was leaving the country with the child, Curran said.
