Sentry Private Investigator's Case Example

Just before Christmas in 2022, we were contacted by a concerned father in Sutton Coldfield seeking discreet private investigation services. He had received information from credible sources that his soon to be son in law was having an affair with a girl from the office. It was only the following month the son in law was due to marry the daughter, so emotions and stakes were high. The father put his trust in us as private detectives to confirm or dispel the rumours so we needed get a result for him.
We were tasked to attend the son in laws work Christmas party in Birmingham city centre to keep an eye on him, and his bit on the side. The party had already finished by the time we got there and the son in law was no where to be seen in the hotel venue where it was held. We quickly went into search mode with a slight panic because Birmingham is a big, and busy place. We first checked the bar next door and to our own amazement, we found him. He was amongst lots of his colleagues and already quite merry as they occupied almost half of the bar. We soon identified the female he was interested in as they subtly locked eyes on more than a few occasions.
As the night went on, the workforce got very drunk and careless. The son in law and his new girlfriend got closer and closer and we knew something was going on. It was clearly not going to end in this bar so we needed to cover the exit and ensure they didn't slip out together without us knowing.
At around 11pm they slipped out the door, but not without us seeing it. We proceeded with a foot follow through Birmingham city centre to the hotel we could only assume the son in law had pre-booked. They were hanging all over each other on the way there and all the way up to the point of their assent in the lift to his hotel room. Our private investigation was a success, but an absolute disaster for the client. We immediately sent the photographic evidence over to the client who was understandably distressed. We can only image what his daughter was going through.
If you have concerns with infidelity in your relationship and you are considering hiring a reputable private investigator company based in Birmingham or in the West Midlands region, get in touch with SPI. Our experienced team is on call to guide you through the process and support you through what we know can be a very stressful time.
