A FECKLESS mum went out partying all night leaving her four-year-old daughter home alone, a US court has been told.

Alexandra Ciliento left her apartment in Scottsdale, Arizona, at around 11pm on Saturday night without anyone to care for her child, according to reports.

While the 29-year-old was enjoying her night on the tiles her daughter eventually escaped the family home and headed over to a neighbour’s house at 6:30am the following morning, according to Fox 10.

The neighbour reportedly waited 45 minutes for Ciliento to return before calling the cops who finally managed to reach her shortly after 8am on Sunday.

When she returned home she told Scottsdale police she left her apartment at 11pm the night before to go to the local entertainment district, AZ Central reports.

"No plan was set in place to have the child watched by a family member or guardian. Nor was there any attempt made to secure a babysitter," police said in court records.

Cillento reportedly told police that she “was not aware that her child could open a locked door and leave the residence”.

Her daughter is now in the custody of her dad with Ciliento reportedly banned from seeing her.

She was charged with one count of felony child abuse.
