Two robberies and at least one carjacking on the city's east and northeast sides are believed to be the work of a 15-year-old boy, San Antonio police said.

San Antonio Police Department Sgt. Patrick Day said officers were called to a Shell gas station on Rittiman Road near Interstate 35 around 4 a.m. Thursday for a report of an attempted carjacking.

Day said someone tried to steal a man's pickup at gunpoint. He said "almost simultaneously" police received a call for a robbery of an individual at a Valero Corner Store just down the street on Rittiman Road near Goldfield.

The second victim, who said he had just pulled off the highway due to car problems, told police he handed over his cash to a person with a gun.

"(The robber) did demand a vehicle at the Shell station, and he did get some money from a complainant over here at the Valero," Day said. "Based on the information given by the two callers, they described a suspect, clothing."

Day said in both cases it appeared police were looking for the same man.

"The officers were close and they quickly set up their quadrant and were able to apprehend the suspect," Day said.

Officers soon spotted someone matching the description walking down Rittiman Road near Fratt Road.

After a short foot chase through a nearby field and apartment complex, police said, they took the boy into custody.

Day said the teen told officers he was a runaway and doing what he needed to survive.

Police believe the same teen also stole a car at gunpoint from someone on W.W. White Road during the overnight hours.
