Some tense moments Wednesday night at Newark Liberty International Airport after a suspicious package caused an evacuation of Terminal C.

Photos posted on social media showed crowds of people inside the terminal and a heavy police response outside the airport.

Authorities said the suspicious item was placed in a trash can in the terminal. Officials said the item was determined to be a pressure cooker that would be used in a kitchen and was deemed not harmful.

Port Authority officers gave an "all-clear" a few minutes after responding to the scene around 7 p.m. Wednesday.
