A man who was under arrest in a Maui meth trafficking investigation bit two officers after he refused to go back into a holding cell, authorities said.

Edward Vierra was arrested Monday on Maui after he received a package of methamphetamine mailed from California to Maui, according to a criminal complaint filed in federal court.

After he and a co-defendant were taken to Honolulu, Vierra asked to use the restroom. When he was done, he refused to return to the cell and bit the officers, authorities said. It was not clear where the officers were bitten.

A scuffle followed, leaving one officer with a forehead scrape and another with rib injuries, the documents state.

Vierra and co-defendant Kelly Eleneki were scheduled to appear in federal court Thursday for a detention hearing.

Vierra’s attorney couldn’t immediately be reached for comment. Eleneki’s defense attorney, Jason Say, declined to comment.

The case involves two packages mailed to Wailuku containing a total of about 7 pounds of meth, the complaint said.

The U.S. Postal Inspection Service intercepted the first package on July 29 and the next day, a postal inspector posing as a mail carrier delivered the package while agents watched.

Soon afterward, Eleneki was seen leaving the home driving a pickup truck with the parcel inside, the documents said, adding the truck was followed by a sedan driven by Vierra. Both vehicles drove to sugar cane fields where the parcel was left, unopened, the document said.

On July 31, the second parcel bound for the same address was intercepted. An unknown man took the parcel on a dirt bike. Authorities tried to pull him over, but he fled, the complaint said. The package was later found unopened in the middle of a sugar cane field.

When authorities went back to the house where it was delivered, Vierra was seen leaving a second small residence at the same location, authorities said.

An unknown man yelled out to Vierra, "Get rid of your backpack," and he began running and discarded the backpack, the complaint said.

Inside the bag, authorities found a large amount of cash and a digital scale.
