When to Hire Private Investigators in Sydney

There are many reasons why people hire private investigators in Sydney – from finding missing persons, online harassment cases, skip tracing, employee background checks, and even for CCTV installation in Sydney.

Everyone has a sense of instinct and intuition, and if you have a feeling that something is off, it usually is. If you'd like to gain clarity on a situation, want to resolve workplace matters, or gather admissible evidence for a legal court case, hiring a private investigator in Sydney might be the best next step.

Real Client Outcomes

One of our clients, a successful businessman from interstate, had become involved in a relationship with a woman in Sydney. Suspecting that something was going on with his partner, our client engaged Lyonswood Investigations to learn the truth.

Our private detective in Sydney placed the female under surveillance to see what she got up to when her partner, our client, was out of town. On the first morning of surveillance, we established that she was in a relationship with another man. However, we also discovered that she and her partner had committed a number of serious property crimes with her boyfriend, and they used the proceeds to purchase illegal drugs.

We also followed the female to court, where our private investigator in Sydney saw her defending separate criminal charges, which our client was unaware of. Furthermore, our client had been supporting the woman financially as she had reportedly been dealing with a serious illness. Our investigations revealed that the illness was a lie.

As this case study shows, wrongdoing is often a pattern of behaviour, and if your intuition tells you that something is wrong, you're usually right. If you're involved with a partner, employee, competitor, regulator, family member, litigant, or organisation who you believe is engaging in dishonest or illegal activity, speak to one of our private investigators.
