Port Authority Trans-Hudson (PATH) train service in New Jersey returned to normal late Sunday night after a bomb threat led to disruptions, officials said.
"An emotionally disturbed person made a threat to the PATH station in Harrison" Port Authority spokesperson Steve Coleman said in a statement.
The Port Authority of New York and New Jersey, a bi-state agency created by an act of Congress, operates the PATH system between New York City and New Jersey. It is one of the busiest mass transit train operations in the world, carrying hundreds of thousands of people each day.
The Port Authority also operates bridges and tunnels between the two states, as well as JFK, LaGuardia and Newark International airports.
PATH service was disrupted in New Jersey as police investigated the threat. Service returned to normal shortly after 11:30 p.m.
NJ Transit was cross honoring PATH ticket-holders.
No word on whether an arrest has been made in the case.
