Marana Police are still investigating a series of break-ins on the northwest side; they want businesses around Ina and Thornydale to stay alert.
Just last night Jiffy Lube was hit and about $200 were stolen.
Earlier this month two other automotive shops, a dental and animal clinic were broken into.
Police responded to these four burglaries in just two days a couple of weeks ago. Police believe it could be the same person or a group of people doing it.
In each instance a rock was thrown through the window to get inside and petty cash boxes were stolen.
Police are taking extra precautions and have additional officers patrolling the area.
Marana Police and the Pima County Sheriff's Department are both investigating the series of break-ins. They are urging businesses to lock their doors, keep valuables locked away and have alarm systems in place.
Anyone with information is asked to call Marana Police at (520)682-4032.
