A woman left her 3-year-old son alone at a METRO bus stop, investigators said.

Latoshiah Perkins, 28, was charged with abandoning a child.

Harris County Precinct 7 deputy constables said Perkins left her 3-year-old son and her purse at a METRO bus station in the 8000 block of Martin Luther King Boulevard while she got on a bus on Aug. 30.

A stranger saw what happened, watched over the frightened child and flagged down a deputy constable.

Perkins was arrested as soon as she returned to the bus stop.

On Facebook, Perkins described herself as a stay-at-home mother.

Perkins pleaded guilty Tuesday and received two years probation with deferred adjudication.
