Frisco police say the city is seeing a sharp increase in car burglaries.
The number of vehicle break-ins increased by nearly 50 percent in the first quarter of the year as compared to last year. It is the most significant quarter-to-quarter increase in five years, police said.
Police are also concerned because petty crime rises as temperatures warm.
"We know it's a trend that they're probably going to go up when the weather warms up," Officer Jon Skertich said. "People leave their cars open, windows down. It takes about 30 seconds for a bad guy to break into the car."
People simply are not locking their vehicles or securing their belongings, police said.
"One out of three vehicles that have been burglarized, the officer goes to the scene and only one of three of those was a forced entry where they're punching a door lock or breaking a window," Skertich said.
The mode of entry in some cases is undetermined, but police estimate that as many as half of the break-ins happened to unlocked vehicles.
Police and city leaders are promoting a "Take, Lock, Hide" campaign to raise citizen awareness of the problem.
The most common areas for vehicle break-ins are around Stonebriar Centre Mall and the shopping plazas at Gaylord Parkway and Preston Road.
