Federal investigators believe a man arrested Friday at his father’s home near Cotswold was distributing methamphetamine, according to court documents unsealed on Tuesday.

Raumeen Shiraz, 24, of Charlotte, is charged with unlawful distribution of a chemical used to make meth, possession of the drug with intent to distribute and possession of a firearm by a convicted felon.

During a Wednesday court appearance, a judge ordered that Shiraz be held behind bars until another hearing next week.

Law enforcement agents seized a 100-pound container of iodine from the home, according to a criminal complaint. The chemical is one of several used to make meth.

At a storage unit on Park Road used by Shiraz, authorities found a plastic bag with 315 grams of the drug, a hotplate plugged into a light fixture and several other chemicals, according to the complaint. Authorities say they also found four guns in a black trash bag.

In 2010, Shiraz was convicted of possession of a firearm by a felon and was being monitored by state authorities as part of his probation, according to the complaint. In September, probation officers contacted the FBI after they did a spot check of the home and found more than 30 chemicals in his bedroom that could be used to make narcotics.

Shiraz told FBI agents that he had obtained a new business license and was doing business as Shiraz Lab Supply, according to the complaint. He told the agents he did all his transactions on the computer and made between $80,000 and $90,000 a year shipping chemicals domestically and internationally.

But authorities say Shiraz is not authorized to ship the chemicals.

“Mr. Raumeen Shiraz” is listed as a contact person for a business called “Reagents for Chemicals,” which sells wholesale chemicals on the Internet, according to a Web search conducted by the Observer.

“I offer chemicals to anyone, i know how hard it is to get chemicals now days with out a business license,” the website reads.

The address for the company is the home on Robinhood Road, which was raided by investigators on Friday.

In October, U.S. Immigration and Customs Enforcement agents seized a chemical that could be used to make another controlled substance. The substance was imported from China and addressed to Shiraz.

Earlier this year, undercover DEA agents bought iodine crystals from Shiraz on eBay and through www.shirazlabsupply.com.

In May, FBI agents began following Shiraz. They saw him mail packages from a post office near his home.

They also followed him to a storage unit. After leaving, agents say, he engaged “in a series of what appeared to be counter-surveillance maneuvers.”

The storage unit was registered under the name Clarence Boddicker. That’s the name of the villain in the 1980s movie “Robocop.”

One of the contact numbers provided to the storage facility was phony. It was the telephone number of the Mecklenburg County jail, where Shiraz is now being held. Staff researcher Maria David and Elisabeth Arriero contributed.
