Suffolk police evacuated the Port Jefferson ferry Wednesday afternoon after a passenger was overheard discussing the potential to put a bomb on the boat, authorities said.
Police determined the incident was noncriminal and no explosives were found.
Authorities said they received a 911 call at around 1:20 p.m. concerning a passenger who had been discussing the possibility of putting an explosive on the ferry, which is operated by the Bridgeport & Port Jefferson Steamboat Co.
Police interviewed passengers, who were asked to disembark at the Port Jefferson ferry terminal, and determined the incident was a "misunderstanding," police said in a statement.
The ferry was headed for Port Jefferson.
Officials with the Bridgeport & Port Jefferson Steamboat Co. did not immediately respond to a request for comment.
