A man has been charged with alleged drug offences following investigations into a fire at a Lake Macquarie industrial site last week.

Shortly after midday on Friday (20 May 2016), emergency services were called to an industrial site on Kalaroo Road, Redhead, following reports of a fire.

On arrival Fire & Rescue NSW crews extinguished the blaze and uncovered an alleged hydroponic set-up.

Officers attached to Lake Macquarie Local Area Command searched the premises and allegedly located 38 cannabis plants, more than 8kg of cannabis leaf and more than $35,000 in cash.

All items were seized for forensic examination and a crime scene was established.

Following investigations, a 52-year-old man attended Belmont Police Station yesterday (Sunday 22 May 2016) and was arrested.

He was charged with deal in proceeds of crime, supply prohibited drug, cultivate prohibited plant and possession of prohibited drug.

The man was granted strict conditional bail to appear before Belmont Local Court on Wednesday 29 June 2016.
