The number of overnight residential break-and-enters is rising across Calgary, according to police.

There have been more than 30 reports filed in the past several weeks, police say.

Most happened between 11 p.m. and 7 a.m., while the victims were asleep inside their residences.

Entry was often gained through unlocked windows and doors.

Vehicle keys as well as various valuables left out in the open were targeted in the incidents.

More than 20 vehicles were stolen in the incidents.

Police suggest locking windows and doors even when home and not leaving items in obvious places.

Police also suggest investing in a safe, motion-activated or timed lights, alarms or cameras.
