Clip may have been filmed in Hong Kong, but exact location is not clear

A giant snake terrified diners after it suddenly dropped down from the ceiling at a restaurant.

Footage shows the 20ft-long reptile coming through the ceiling tiles in front of shocked customers.

The video shows the snake being guided out by workers at the restaurant using a metal hook.

It is not clear exactly where the footage was filmed, but people in the video can be heard speaking Cantonese, suggesting that it may have been in Hong Kong.

One person can be heard saying: 'Look how big it is!' Another adds: 'How disgusting!'

A man in the video can be heard suggesting that the snake is around 20ft-long.

The workers firstly used the pole to make a bigger hole in the ceiling in order to allow the snake to come out.

They can then be seen using their hands to pull the giant snake down to the ground.

Earlier this week, plane passengers were left terrified after spotting a poisonous five-foot-long green viper hanging from the overhead lockers.

This video was reportedly taken on an AeroMexico flight from Torreon to Mexico City on Sunday.
