Authorities say two teenagers attempting to carjack a vehicle in Houston were foiled by a stick shift.

The pair held the motorist at gunpoint last weekend and demanded that he tell them how to drive the vehicle. After the driver provided a few instructions, the teens ordered him out of the vehicle. He then called police.

A brief police chase ensued. Stefan Happ, an officer for the University of Texas at Houston, told KPRC-TV (http://bit.ly/1tJoDw9 ) the teens "had issues operating the vehicle."

The pair opted to flee on foot and were later apprehended.

The suspects are 15 and 17 years old. They were taken into custody. The older boy was charged with aggravated robbery with a deadly weapon.
