The methods used in the probe evoked a Monty Python sketch. The deputy mayor of Septemvri was ordered personally to dig a hole in the street using a spade so that a police investigator could use a tape to measure the water pipes. As the digging progressed, a telephone line was cracked and the people in the neighbourhood lost their phone and Internet connections. A local who did not know the police probe was going on and did not expect a hole where there had been a road... drove into it, damaging his car.
In addition to the water pipe, a local city council road had to be measured, using the odometer of a police car, against the protestations of the police who said the measurement might not be very precise as the car's tyres were low profile. Probes were then taken from the road to verify whether the amount of sand and gravel used was right.
The state prosecutors and the police left the water pipe hole open, then the Septemvri City Council refused to pay for its repair.
It is unclear whether the evidence collected in this way was used against the mayor of Septemvri, but the police refused to issue the man who smashed his car with a police report. Instead, a uncalled-for towing truck appeared to pull the car out of the hole.
The man was infuriated as he needed the report to file insurance claims. The police responded he himself had refused to be issued a report, a claim the man vehemently denied. Asked who had called in the towing truck, the police said they didn't know. The service, however, was free.
