Update: Boy has 'thief' inked on his forehead, tattoo artist arrested

UPDATE: The two men involved in the inking of the boy's forehead have been arrested and charged with torture.

The two suspects, aged 27 and 29, have admitted to carrying out the actions caught on video.

After the boy was caught by the duo stealing a bike, the pair tied him up and forced him to be tattooed.

"I asked them to make the tattoo on my arm but they said they would do it on my forehead and started laughing," he told Folha de S.Paulo newspaper.

"I begged them to break my arms and legs instead."

Furious viewers on the internet have now started a campaign to help the boy have the ink removed.

Read the original story below:

A terrified teenage boy, who allegedly stole a bicycle from a man with one leg, was caught by a tattoo artist, who proceeded to ink his forehead.

The words 'I am a thief and a loser' are sure to humiliate the teenage boy forever.

This footage is quite disturbing. 

In a chair sits a clearly distraught boy and the sound of the tattoo artist laughing and talking can be heard as he scribbles the damning words on the boy's forehead.

After inking him, he then cheekily asks if the embarrassed teenager likes it?

Local reports say that the boy, who seemed terrified while the artist drew on his head,  had gone missing on Friday.

His family then saw the video of the inking and reported the tattoo artist to the police. 

I know what this boy has done is wrong. Stealing is never right, but in my opinion, to tattoo someone like this is far worse.

You can literally see the fear in this boy's face and he's obviously been humiliated enough in the past, hence why he disappeared.

I would have liked to see this tattoo artist take this young boy under his wing and perhaps teach him his own trade or get him some help?
