A 41-year-old man is accused of showing up to work with a gun and threatening to kill his co-workers before cops allegedly found cocaine, fentanyl and other drugs in his car.

West Bridgewater man Dwayne Richardson was arrested last week in Winthrop with a cache of drugs and a loaded gun in his BMW.

Winthrop cops last Wednesday received an alert for a white 2018 BMW that Richardson owns. Earlier that day, Richardson had allegedly gone to his Malden workplace with a gun and threatened to kill the staff.

Then a day later, Winthrop officers stopped the BMW on Revere Street and arrested Richardson.

Cops allegedly found $5,090 in cash, a 634.2-gram brick of cocaine, 29.7 grams of fentanyl, 8.4 grams of oxycodone, and 3.6 grams of Adderall in his vehicle.

Police also searched Richardson and allegedly found several clear plastic bags of crack-cocaine, fentanyl, and cocaine.

Officers found a Springfield Armory XD5 pistol in the BMW’s trunk.

“Anytime police can take deadly drugs and illegal guns off the street it’s a win for public safety,” Suffolk DA Kevin Hayden said in a statement.

“The reports of this defendant using a gun to threaten co-workers in the earlier incident adds to the danger posed during this entire episode,” he added.

Richardson has a previous criminal record, including multiple violent and drug related charges dating back to 1992.

He served 10 years behind bars stemming from a conviction in Middlesex Superior Court for illegal possession of a rifle, and two counts of illegal possession of a shotgun. He was released last year.
