Prosecutors in Paris said on Thursday no suspicious items had been found.
Goldman told staff they could work remotely on Thursday, a source familiar with the matter said, while employees at Citigroup in Paris and Frankfurt also worked from home as a precaution. Citigroup said the move was a precautionary measure.
The heightened alert followed a foiled bomb attack near the Paris offices of Bank of America last week.
French anti-terrorism prosecutors said a man and three teenagers aged 16 and 17 had been placed under formal investigation and held in pre-trial detention on suspicion of manufacturing, transporting and handling an explosive device and attempting to destroy property as part of a terrorist organization.
They said the device, made from a five-litre petrol can attached to a large pyrotechnic charge containing a 650-gram active-material cylinder, was the most powerful of its kind identified in France and could have generated a fireball several meters wide.
Investigators said the adult suspect recruited the teenagers, paying them between 500 and 1,000 euros to plant and film the device. All four denied terrorist intent.
Authorities said the plot may be linked to a pro-Iranian group known as HAYI, which had posted a video naming Bank of America’s Paris headquarters, though prosecutors said the link had not been formally established.
