Four suspected associates of a Mexican heroin cartel were arrested at Secaucus, New Jersey hotel Tuesday as they were allegedly moving drugs through the state.

Drug Enforcement Administration officials and New Jersey State Police said 31 kilograms of heroin was seized. Photos released by law enforcement officials show some of the drugs were being carried in gym bags.

The drug task force raided a room at the Extended Stay Hotel where the suspects were allegedly hiding out. NYPD officers and New York State Police assisted in the investigation.

The raid come less than a week after 100 pounds of heroin was seized in the back of a pick-up truck in Queens.

Oscar Renen Felix, John Ulloa, Anthony Ross Koon and Alan Martin Alderman are expected to appear in court late Tuesday on state drug conspiracy charges, officials said.
