BOSTON (AP) – A former Malden police narcotics investigator on Wednesday was sentenced to serve 15 years in prison for cocaine trafficking.

David Jordan, 45, of Stoneham, allegedly took $15,000 to help drug dealers rob another dealer of 3 kilograms of cocaine.

Jordan and Anthony Bucci, 43, of Wakefield, were convicted in April of charges including conspiracy to distribute and to possess with intent to distribute three kilograms of cocaine.

Jordan also was convicted of attempted witness tampering and three counts of making false statements to federal agents.

Bucci was sentenced Wednesday to serve 21 years in prison.

Jordan, Bucci and two other men conspired to steal cocaine from a dealer during a scheduled drug deal in a Malden parking lot on Christmas Eve 2003, according to federal prosecutors.

Jordan showed up at the scene, identified himself as a police officer, blocked the dealer’s vehicle and held a gun to the dealer’s head while another man in on the plot grabbed the cocaine, prosecutors said.

Agents for the U.S. Drug Enforcement Agency observed the incident as part of another investigation, prosecutors said, and began investigating. Jordan made false statements to DEA agents about his involvement.
