Security was scrambled at the London building sparking international concern Assange was the target of the intruder.

A statement was put out by WikiLeaks this morning.

It stated: "16 mins ago at 2:47am a "cat burgler" scaled the side wall+window of the Ecuadorian embassy in London; fled after being caught by security."

Mr Assange has been living inside the embassy for more than four years and has been granted political asylum by Ecuador.

Fans of Assange took to Twitter to suggest he may now be in danger inside the embassy.

One wrote: "Here we go. I hope Mr. Assange knows what he's doing. Hope he leaves his information with others in case of an accident."

Another said: "Somebody is definitely out for Assange. I really do hope Assange has some great intel for us once he's done redacting."

Some suspected American involvement.

One Twitter user wrote: "@wikileaks Maybe one of Hillary's assassins? #saudimoney #neverhillary"

Another said: "@wikileaks attempted assassination you think?"
