"The police said wait here until they come and get us," one person says in the video.

The footage also shows a frightened woman whose labored breathing quickly turns to tears.

A few still have drinks in their hands as some men put their ears to the door to hear what's happening outside.

In another video that recently surfaced online, a London cop in the basement of another bar admonishes dozens of patrons found cowering in fear.

"We are chasing victims around London who want to kill people," he says. "They are going into buildings looking for people. Ok? You are all clumped together in a place with no exit route. Ok? You are victims waiting to happen! Get your stuff, and get out of the danger zone! Now!"

The three terrorists responsible were gunned down by police Saturday night and have all been identified.

The ringleader is believed to be 27-year-old Khuram Butt.
