Police are investigating after two vehicles and a home were set alight in Charlestown overnight.
Lake Macquarie police said a Hyundai i30 was found on fire at a home on Whitburn Close sometime between 5.30pm and 8pm on Wednesday, October 23.
Neighbours and Fire and Rescue NSW assisted in extinguishing the blaze.
Officers from Lake Macquarie Police District were called and attended the scene.
While at the Whitburn Close home, police received reports of another vehicle fire on Merran Avenue in Charlestown.
Police have been told a man noticed his vehicle, a Subaru Forester, was on fire and extinguished the blaze.
He then noticed two separate small fires at the sides of the home. All the blazes were extinguished.
Officers from Lake Macquarie PD were called to the scene and launched an investigation.
Police believe the two incidents are linked.
Lake Macquarie Police District duty officer, Chief Inspector David Matthews, said this is a timely reminder for residents to revisit their home security.
"Always try to park vehicles inside a garage where possible, never leave valuables inside your car and in plain sight, and always remember to lock the door before walking away," he said.
"These may seem like simple reminders but they can help you avoid becoming a victim of crime."
Police are appealing for anyone who may have CCTV or dash cam footage from the area around these times to contact Belmont Police on (02) 4922 8899 or to call Crime Stoppers on 1800 333 000.
