HOUSTON -

Houston police have released the name of the man accused of stealing a day care van with five children inside from a southwest Houston fast food restaurant.

An Amber Alert was issued Wednesday night around 8:30 p.m. after Brenton Alex Simmons, 24, allegedly hopped inside the van and drove off with the children.

Police said a day care worker left the two girls and three boys  alone inside the running vehicle at a Jack in the Box in the 8600 block of West Bellfort at South Gessner.

Bobby Johnson was at the Jack in the Box when it happened. After hearing the children scream, he ran outside and started chasing after the van on foot.

Johnson said he eventually lost sight of the van, and that's when he pulled out his phone and called 911.

HPD homicide investigators, in coordination with the Fort Bend County Sheriff's Office and Harris County Precinct 5 deputy constables, located the suspect, children and stolen vehicle at 22300 Cinco Ranch Boulevard in Fort Bend County around 9:15 p.m. They were able to find the children using a GPS signal from a cellphone inside the van.

The children were reunited with their parents Wednesday night.

The children, who were all between 3 and 6 years old, were unharmed. 

The van  transports children to different day cares.  Police said the driver may face charges as well.
