COPENHAGEN (Reuters) – Four Danish Uber drivers [UBER.UL] were on Monday found guilty of illegal taxi driving by a Copenhagen court, with one driver fined about $78,000.

The four drivers were charged in March after the Danish tax authorities received a list from the Netherlands of around 1,500 Danish Uber drivers’ names, Danish police said in a statement.

One of the four drivers was fined 486,500 Danish crowns ($78,060) for having made 5427 illegal taxi rides as an Uber driver in 2015. The three others were fined between 40,000 and 110,000 crowns, the Copenhagen district court said in a statement.
