The search is on for a missing 12-year-old girl with bipolar disorder, last seen in Newark's West Ward, according to reports.

Iynasha Williams, who ran away Sunday night from her home in Newark, has the mental capacity of a 3-year-old, NJ.com reported.

She was last seen at around 9:45 p.m. at her home on South Orange Avenue wearing a yellow pajama top, pajama bottoms with writing on the legs and black high-top sneakers. She reportedly lives at Harmony House with her mother on South Orange and Littleton Avenues, a transitional housing program for the homeless.

Her hair was braided and is blonde in the front and in the back.

Anybody with any information is urged to call the police department's Special Victims Unit at 973-733-7373.

The missing child comes just one day after 14-year-old Brittany Michelle Navarro, who went missing in Newark's Branch Brook Park in Newark last Thursday, was found safe by a resident on Court Street.
