A New York man has been arrested on charges he offered to sell a woman's two-month-old baby online for $US100 ($A113).
Staten Island prosecutors said on Monday that Paul Marquez was charged with endangering the welfare of a child and harassment.
Authorities say Marquez had been out with the baby's mother a few times but felt she wasn't paying him enough attention.
They say he was angry with her so he posted the ads with photos of her daughter on Craigslist.
The mother notified police after she received a phone call from a person offering to buy the baby.
