A warrant was executed at a residential address in Newtown this morning.

The alleged fraudulent activity spans approximately five years and involves several million dollars.

Detectives have obtained financial and business records from genU, which are currently undergoing forensic assessment.

Investigators are seeking information from anyone who may have knowledge of the matter or those responsible.
