VIDEO: Armed robbers strike Chanel jewellery store in Paris and flee on motorbikes
A combo image shows the robbers fleeing the scene on motorbikes.
Nobody was hurt during the heist, and there was no immediate indication of the bounty's value.
Police said at least one of the four, who were all masked and wore helmets, carried an assault rifle, with a witness saying that the others also had automatic weapons.
They made their getaway on two motorbikes in a scene that was filmed by a bystander and widely shared on social media.
The clip shows three people dressed in black leaving the boutique while a fourth, carrying an assault rifle on a shoulder strap, waited on a motorcycle.
A witness, 26-year-old Anastasia Martino who works in a clothes store across from Chanel said she was on a cigarette break when she noticed "a man with a Kalashnikov on a motorbike", at around 2:30 pm (1230 GMT).
"Two minutes later, three other men left the boutique carrying big black bags. They, too, had automatic weapons, got on two motorbikes and left in a hurry."
Her colleague, 31-year-old Cyril Ngo, said the heist lasted a full 10 minutes. "These weren't professionals," he said.
The Chanel shop is located on Rue de La Paix, close to Place Vendome, an area with a high concentration of luxury jewellery stores.
Police cordoned off the area shortly after the robbery, and the store was shuttered.
Chanel, founded in 1910 by Coco Chanel, is one of France's leading fashion houses, selling haute couture and ready-to-wear clothes, perfumes, accessories and other luxury items.
