French authorities on Tuesday arrested another four suspects in connection with last month's jewel heist from the Louvre Museum in Paris, the Paris prosecutor's office said, DW reports.

"They are two men aged 38 and 39, and two women aged 31 and 40, all from the Paris region," Paris prosecutor Laure Beccuau said. Their role in the robbery that took place on October 19 has not yet been determined. In France, the maximum duration of preliminary detention for questioning can last up to 96 hours.

In the same case, charges had earlier been brought against four individuals: three men (35, 37 and 39 years old) suspected of directly robbing the museum, and a 38-year-old woman suspected of being an accomplice.

According to the investigation, the thieves entered the museum at midday on October 19, using a retractable ladder mounted on a stolen truck and opening a window with cutting tools. As they fled the scene, they stole a diamond and emerald crown and eight other exhibits, including jewelry that belonged to French queens and empresses. The stolen jewels, estimated to be worth around €88 million ($102 million), have not been recovered.
