STATEN ISLAND, N.Y. -- Fuming from a Valentine’s Day spat over a microwave snack, a teen allegedly kidnapped a 3-year-old girl the next night from a male acquaintance’s Mariners Harbor home, said a law enforcement source.

But cops turned Aliyah Austin’s subsequent texted rants to the girl’s father against her and nabbed the 16-year-old suspect yesterday in Brooklyn’s Bedford-Stuyvesant section. The girl was unharmed.

The source said Ms. Austin, a transient, had been living at the home of the victim and her of 29-year-old father for a few days. The suspect had been watching the little girl while her dad went to work.

The source could not immediately say how Ms. Austin met the victim’s father. He declined to divulge the man’s name.

Things turned sour Monday, when Ms. Austin ate the man’s last Hot Pocket. Angered, he allegedly smacked her.

Apparently seeking revenge, Ms. Austin waited until the man went to work Tuesday afternoon.

At about 7 p.m., she grabbed the little girl and left, said the source.

They made their way to the Staten Island Ferry and ultimately to the apartment of the suspect’s friend in Brooklyn.

The source said the little girl had repeatedly begged Ms. Austin, "I want daddy."

The father returned home at midnight and notified police his daughter was missing, sparking a massive search on the North Shore.

During that time, Ms. Austin texted the man and taunted him with Facebook messages, said the source.

"If you want your baby back, meet me at the rock," she texted, according to the source.

The source said authorities aren’t sure whether "the rock" refers to the slang name for Staten Island, the Rockaways in Queens or some other location.

Cops tracked Ms. Austin’s cell phone signal to her friend’s place.

The suspect is charged with second-degree kidnapping and acting in a manner injurious to a child, said a spokesman for District Attorney Daniel Donovan.
