Police have released a woman suspected of being involved in the daytime robbery at France's Louvre Museum under judicial supervision, the Paris prosecutor's office says.

The woman was among four people put under formal investigation in connection with the robbery, whose authors got away with historical jewels worth $US102 million ($A155 million) from the museum's Apollo Gallery, home to the French crown jewels.

She will not be allowed to contact other suspects or to leave France.

Two men parked a movers' lift outside the Louvre one Sunday morning last month.

They rode up to the second storey, smashed a window, cracked open display cases with angle grinders and then fled on the back of scooters driven by two accomplices in a heist lasting less than seven minutes.
