New York police are on the lookout for a 28-year-old Manhattan mom who abducted her eight children from a foster-care facility.

Police said Shanel Nadal took her seven boys and daughter without permission from the agency while she reportedly was on a supervised visit Monday with the children at the Forestdale agency in Queens. It's unclear how she managed to take the boys, ages 4 to 11, and an 11-month-old girl.

The New York Daily News reported that Nadal foretold her plans to take the children in a text message the day prior to the incident.

I cannot live without my children, Nadal, wrote to foster mother Amieka Smith on Sunday. I cannot breathe without my children.

A manhunt is under way for the children, who may be with their biological father, 34-year-old Nephra Payne, the Daily News reported.

Authorities said Nadal may be traveling with Payne in a black Chevrolet Suburban, a black Ford sedan or a black Infiniti.

The Administration for Children's Services said Tuesday it's working with the police to find Nadal.

We sought and received active warrants from the Manhattan Family Court for the arrest of both parents and for them to produce the children to the court, children's services said in a statement. We ask for the public's assistance in locating the children, and appreciate any assistance that they can provide the NYPD.
