Wild boars have invaded several gardens in Collégien, alarming residents.

In the commune of Perthes, over 200 caravans have been illegally installed in a field, prompting several complaints from property owners.

A dozen caravans of travellers are also set up at the foot of a housing estate in Marolles-sur-Seine.

Additionally, lambs were stolen in late April and were found with the travellers.
