A FACEBOOK video of a toddler dressed up for Halloween has sparked controversy after thousands of viewers deemed it inappropriate.

In the clip the young boy can be seen dressed up as notorious Colombian drug lord Pablo Escobar, with hair parted to one side, a moustache and brightly-patterned shirt.

Escobar was known, before his death at the age of 44, as “The King of Cocaine” and history’s richest criminal, supplying close to 80 per cent of smuggled cocaine to the US.

The Facebook video, shared by user ‘Break’, has been viewed more than 5 million times since being uploaded.

While some people found the outfit funny, others were less amused to see someone making light of such a dangerous figure.

“Pablo Escobar is more than the king of coke. He is also the creator of narco terrorism which claimed the life of thousands of innocent people. Including little kids like this one”, one Facebook user wrote.

“Lol u lot are idiots it's a child in a costume. The juxtaposition of him being a baby and being a drug dealer its what’s funny. It would have been equally as funny if he was dressed as ANY recognisable adult character. Lol u need to chill and find something better to moan about,” another wrote.
