Gunnedah has been hit by a spate of car break-ins and thefts recently.
On Wednesday, March 13, police said a car was broken into on Favell Street, with thieves ruffling through and stealing multiple items. A car was also reported stolen in the same street.
On the same night, a house was broken into while the occupants were at home in Baxter Street.
Police understand the offenders were disturbed by the occupants and then fled the scene. They stole the resident's Ford Falcon to make their getaway, and it was later found burnt out in Tamworth.
Gunnedah Acting Inspector Mark Benson said these were examples of "opportunistic crime".
"Thieves will try 20 cars and find one that’s unlocked," Acting Inspector Benson said.
"People don't smash windows to get into cars - why do it, when you can just come across one that's unlocked?
"People need to be more vigilant in securing their property."
On Thursday, March 14, Gunnedah police said thieves stole items from a car left unlocked inside the owner's garage.
On the same night, a wrought iron table and chairs were stolen from a verandah in Gallen Avenue.
Acting Inspector Benson told the NVI this unique crime had been "done in the past" and the suspects may be linked.
Two motels were also hit by thieves on Thursday night.
Thieves broke into the office area of the Maynestay Motel on Conadilly Street, where they stole cash. Money was also stolen from the Overlander Motor Lodge on Conadilly Street, police said.
Officers believe a number of these crimes are linked, and investigations are under way.
"It's not like the old days, people are just walking in," Acting Inspector Benson said.
On a number of occasions Gunnedah police have urged residents to lock their vehicles when they are unattended, and to not leave valuables in sight, to take them inside the home or secure them in the boot of the vehicle.
Acting Inspector Benson said the police were using "all leads" to catch suspects, including working with Tamworth investigators.
