Police in Delaware have issued an Amber Alert for a 3-year-old girl who they say was kidnapped by her father after he assaulted her mother.

Police are looking for 43-year-old Michael Trotta and 3-year-old Elinor Trotta, saying they believe the girl "is in imminent danger."

New Castle County Police say the girl's mother called police Monday night to report that her ex-boyfriend had just come to her home, assaulted her, and took Elinor. Police believe Trotta may have fled with the girl to New Jersey or New York City.

He's described as white, 5 feet 8 inches tall, 160 pounds, balding, and with a scruffy beard and mustache. Elinor is 60 pounds with brown shoulder-length hair and was last seeing wearing a purple puffy coat, pink pants and "Frozen" sneakers.
