Police arrested 29 people on Tuesday in connection with an investigation by the tax office into possible tax fraud and extortion and bribery in the window cleaning business.

According to the Telegraaf, this follows a major investigation by tax investigators into the way independent operators are forced into paying a percentage of their income to other window cleaners for permission to clean the windows in ‘their’ streets.
During Tuesday’s arrests guns, ammunition, cars, money and paperwork was seized, says the paper. Several marijuana plantations were also discovered and homes and business premises searched.
In total, 370 officials were involved in the investigation.
