“The footballer was at the mansion on Friday and entered the lake, ignoring the restriction order made by the (environment) secretariat and local police, which showed up there the day before,” the document said.
Brazilian media reported on Friday that Neymar threw a party that day to celebrate the completion of the artificial lake.
A spokesperson for the 31-year-old Neymar declined to comment on the issue after a request from the AP. The Paris Saint-Germain striker can appeal the decision, which will be handed to police for possible prosecution.
The company that built the artificial lake, Genesis Ecossistemas, celebrated the 10-day job on its social media channels. It said the lake is 1000 square meters.
The 46-page city hall document shows Neymar received the maximum fine for each of the violations he is accused of.
It was signed by the city’s attorney-general and also said the soccer player’s father, Neymar da Silva Santos, verbally abused local authorities last week when they came to the mansion to put the construction works to a halt.
Mangaratiba city hall said the illegal construction works cost Neymar about 120,000 Brazilian reals ($40,000).
