Dramatic moment gorilla smashed its way out of London Zoo enclosure

This is the dramatic moment a raging 7ft gorilla threw itself against a window before escaping from his enclosure at London Zoo.

The footage obtained by the MailOnline shows the furious beast smash his full body weight against the glass inches from where zoo-goers are standing. The gorilla named Kumbuka was on the loose for at least 90 minutes after escaping last night.

Armed cops and zoo-keepers eventually shot him with a tranquilliser dart as terrified visitors hid in a cafe and other enclosures.
