Our recent Investigations

“Please see below our recent investigation cases conducted by us”

Recent Case 1

Alpha Investigation Services was contacted by a client from Italy requesting us to do a full background check on a person that was going to be his business partner in Australia. He had provided him all his qualifications but when our client did a simple check on the person, he found that a number of his stated qualifications were not certified and the person also had put his office address as being in the city of Perth Western Australia, but he could find that his would be partner was at that address as he stated on his documents.

Our client needed us to fully establish and find the correct information on the person and report back to him.

So we decided to take on this case and started our investigation.

After 2 weeks into our investigation we were able to find that his would be partner did not have a true and valid qualification as a engineer as stated by him, he did not have an office at the address that he mentioned, we also found that he had been a bankrupt in Western Australia and he was running a small engineering firm from his home address in Perth Western Australia.

We prepared a full and in-depth report regarding our investigations back to our client.

Another Investigation and background check was done and completed by us.

Recent Case 2

Alpha Investigation Services was once more contacted by a husband requesting our services to find and locate an address for his wife that had left him some 6 years ago so he would be able to serve her divorce documents because he wanted to divorce her, but she was only providing him with wrong addresses all the time.

We decided to take on his case and investigate the were about she was residing in truth, after many hours of us doing our investigative work we first learned that she was working for a company in Perth WA.

We then set up a surveillance at her place of work so as we could tail her when she left work, and follow her to where she was residing, we did follow her until she drove her car to a block of units in a suburb not far from were she was working and we were able to follow her to her unit.

Now we had the address and her unit number.

We repeated this surveillance over 3 extra days to make sure that she did resided there.

We prepared a full report of our investigation results back to our client.

She was pleased and asked us if we were also able to serve him in person with the family documents once her solicitor had prepared them with his new address, we stated to her that, yes we would be able to do it for her because this was another service that we offered.

Another investigation done and completed by us.

She was only sure that the property they lived in was in both names and a office in the city of Perth WA.

Her mother needed all information found because she was about to commence a divorce on him and needed the true facts and documentary evidence.

We decided to take on her case and after many hours and days into our investigations, we were able to find that her husband had a number of properties in different names and trusts , but during our further investigations all properties did revert to him.
