WARREN (WWJ) - Nearly six kilos of heroin are off the streets and a suspected drug trafficker is arrested in St. Clair Shores.

It was a DEA investigation that spanned the country reports WWJ's Zahra Huber.  Federal authorities intercepted a heroin delivery that started in Texas -- confiscated 5.6 kilos of heroin -- but continued with the "drop" in the city of Warren.

Police say undercover agents sold fake heroine to Maria Leyva, a suspected drug mule.

From there, police say Leyva went to a hotel in St. Clair Shores -- where she was supposed to meet an intended buyer -- who never showed.

Leyva was arrested and taken back to Warren and has been indicted on a charge of possession with intent to deliver.

The case remains open as the authorities continue to investigate.
