A new report offers more details about how a student with special needs managed to walk out of her Brooklyn school and disappear for days, but no school employees will be disciplined.

Nashaly Perez, 15, and three of her classmates slipped out of P.S. 371 in Sunset Park in late September.

The special schools investigator said there was no misconduct on the part of employees.

The principal had been reassigned but is now reinstated.

Nashaly was missing for three days before she was found at a friend's house.

Her family said she has the communication skills of a 7-year-old and needs to be under full-time supervision.

Nashaly's mother told NY1 that the school didn't tell her her daughter was missing until she went to pick her up.
