The Paris court handling investigations into presidential candidates Francois Fillon and Marine Le Pen has been evacuated this morning after a bomb threat.

Sources have described the evacuation as "massive" and suggested the bomb threat to the structure in the city's 9th arrondissement was credible.

Police were sent to the scene after they received an anonymous call informing them a bomb had been left in the building.

A spokesman confirmed the usual procedure of checks was in progress as the building was in lockdown.

Roughly 100 people were evacuated from the building, according to local news outlet Le Parisien.

The news comes just days after an explosive device detonated at the Paris offices of the International Monetary Fund, and a would-be attacker was shot dead at Orly airport in the south of the city over the weekend.
