SAN ANTONIO -

A 2-year-old girl wearing nothing more than a diaper was found wandering a busy San Antonio street early Tuesday morning.

An off-duty VIA transit officer found the toddler around 12:45 a.m. at San Pedro and Lovera Boulevard.

The transit officer called police and SAPD officers went to a nearby apartment complex in an attempt to find where the toddler lived.

They discovered an open door at the Olmos Terrace Apartments and awoke the person inside. Police said a man came to the door and identified the child.

Police said the toddler's parents were apparently at the hospital with another sick child and a cousin was left to watch the girl, but fell asleep.

CPS officials are investigating the case. No charges have been announced.
