The drugs seized in a raid on a Pennsylvania ecstasy distribution center appear to be fentanyl, a potent opioid that’s commonly used to treat heroin addiction.
A search warrant was issued Tuesday and authorities are seeking the owner of the facility.
Authorities seized nearly 5 tons of drugs, including fentanyl, which is an opioid that can be mixed with other drugs and can be abused.
The Drug Enforcement Administration is investigating the operation.
Authorities have said that the ecstasy distribution hub in the northern part of Pennsylvania was set up in the summer of 2016 to distribute the drug.
Officials said they seized more than 2.5 tons of fentanyl from the facility and said it will be analyzed for its potential link to the fentanyl deaths in New Jersey.
