A 16-year-old pizza delivery boy was arrested on Saturday for raping a woman in her Upper West Side home with her 7-year-old daughter sleeping next to her.

Prosecutors say Cesar Lucas of the Bronx admitted to the assault and "that he went in because he was feeling horny and that he took advantage of her."

After the attack, Lucas also allegedly stole an iPhone and $20 from the victim's daughter before fleeing.

The 35-year-old victim told The Daily News, "I screamed. It took him about 30 seconds. I said, ‘Get off of me,’ and I pushed him."

Lucas was employed at Sal's Pizza on 10th Avenue in Hell's Kitchen. He had a prior arrest stemming from another break-in in August, when he stole a woman's wallet after delivering pizza to her neighbor.

Although Lucas' family and co-workers allege they were unaware of the previous arrest, one Sal's employee said, "Absolutely, he should have been fired [after the August incident], but we didn’t know anything."

Lucas has been charged with rape and burglary.
