Police arrested four Israelis with French citizenship and are investigating them for importing and selling drugs, conspiracy to commit a crime and attempted murder, spokeswoman Luba Samri says.
Their remand has now been extended until December 31.
After receiving a tip about the drug ring, the police opened their case in November, the police say.
The four charged in the crime are Emanuel Amueyel, Dan Ben-Tulila and Sarah Ben-Abu, as well as Jerusalem resident Yossi Gabbai, a.
Detectives found that Amueyel contacted young women in France who were willing to hide the cocaine within their bodies in order to avoid detection, and travel to Israel. Once they arrived in Tel Aviv, his partner Ben-Tulila would take the cocaine from the young women and pay them €3,000 (NIS 12,800), police say.
However, when Amueyel discovered that there may be a romantic relationship blossoming between his ex-girlfriend — a former drug mule — and his partner Ben-Tulila, Amueyel decided to kill Ben-Tulila, police say.
Amueyel then traveled to Israel, presumably in order to murder his partner, but was captured by police in Tel Aviv in November. A few days later, police also picked up Ben-Tulila, Ben-Abu and Gabbai.
