A Glen Cove man is facing serious charges following an eight-month investigation that led to a major drug bust.

Police say their investigation began with a near-fatal drug overdose in May 2022.

Glen Cove authorities working with a DEA Task Force arrested 29-year-old Derrick Dyer on Friday.

Glen Cove Police Lt. John Nagle said they were led to Dyer "through cell phone records and some other means that linked him to the original sale of drugs."

The DEA Task Force and Nassau Narcotics Unit worked with Glen Cove Police on the eight-month investigation.

Police say undercover agents conducted three drug buys with Dyer. Each time, they say Dyer allegedly sold them pills that were laced with fentanyl.

Detectives allegedly found Dyer in possession of cocaine and illegal pills during the arrest and have accused him of multiple drug sales.

Among the items police say they found during a search of Dyer's Madison Avenue home in Glen Cove were an assault rifle, high-capacity magazines, a loaded handgun, a bulletproof vest, five pounds of marijuana, cocaine, illegal pills and more than $6,000 in cash.

He is facing charges including criminal possession of an assault weapon and criminal possession of controlled substances.

Police also say he has three prior arrests for criminal possession of a controlled substance, criminal mischief and violating a court order of protection

Dyer vehemently denies the new charges. After making bail, he told News 12 Long Island in front of his house that he is a victim of bad policing.

“I feel like I've been attacked, and I've been framed,” he said. “I feel like they targeted me.”

Despite Dyer’s claims, authorities maintain that they have the evidence to prove their case.

“If you're going to deal fentanyl and drugs, don't do it here in Glen Cove,” Nagle said.
