BRUSSELS: Thieves used sewers to carry out the bank robbery in Belgium.
Police arrived and they found the bank door shut with about 30 deposit boxes emptied inside.
The thieves appear to have had to squeeze through sewage pipes as narrow as 40cm (15 in) wide, before boring another tunnel to reach the bank.
Els Liekens of the water company, Aquafin, said the robbery had been very risky.
“First of all, digging the tunnel towards the sewage system was dangerous for the robbers themselves because of a possible subsidence,” she said.
“And inside the sewer, you have all kinds of danger, such as gas concentrations coming from the waste water.”
Bank customers have been upset at a lack of information from the bank, with some saying the boxes contained their life savings.
