A Mastic man was re-arrested and charged with criminal possession of a controlled substance Saturday – one week after his original arrest created a rift between Suffolk police officials and the district attorney's office. 

It all started last week when Corey Robinson was arrested for alleged distribution of the deadly drug fentanyl, an A-1 felony.

That charge was later dropped by the district attorney's office after two lab tests performed by U.S. Customs and the Suffolk County Crime Lab showed that there was no pure fentanyl in the package that was shipped from China to John F. Kennedy International Airport. 

Two 1-pound bags of powder, police say, were then delivered to Robinson's address in Mastic, where a search warrant was later conducted.

Robinson was re-arrested and charged with criminal possession of a controlled substance in the fifth degree. He plead not guilty and was released.

The district attorney's office had accused Suffolk police of knowing that there was no fentanyl in the bags, but charging Robinson with an A-1 felony anyway.

His attorney is blaming the Suffolk County Police Department for the mistake. 

"They drag his name through the mud. They shot his dog. They arrested his aunt and uncle for doing nothing for being in their own house," said attorney Robert DaPelo. "I've never seen this level of incompetence on the part of police or this level of people making statements that are absolutely, positively not true."

Suffolk County police said even though the lab reports show no pure fentanyl, it was an illegal controlled substance that could be lethal if mixed with heroin. 

"They have illegal drugs on them. It doesn't matter what the name of them are. If they are scheduled as a controlled substance and illegal in New York state, the arrest is warranted and felony charges are warranted," said Assistant Police Commissioner Justin Meyers. 

The bags of powder have now been sent to a lab in Pennsylvania for further testing.

The controversy comes as Commissioner Tim Sini is running for Suffolk district attorney, and after current District Attorney Tom Spota was indicted on federal corruption charges.

If found guilty, Robinson could face up to seven years in prison.
