Richard Dawkins, British evolutionary biologist, took to Twitter to further criticise Ahmed Mohammed, the "clock boy" who had an audience with US President Barack Obama, comparing him to the Isis child executioner.

The 14-year-old boy, Mohammed, had been arrested in his school in Irving, Texas for bringing a homemade clock to school which authorities thought was a bomb.

He was, later, honoured by Google and visited the White House after being invited by the President.

The scientist, Dawkins, reacting to Mohammed's family's demand for $15 million as damages and apology from the Texas government, took to Twitter calling him a "hoax boy" who ""hoaxed his way into the White House."

This was not the first time that the scientist had expressed his disapprobation about the child who called the clock his invention, reports Time. Judging the attempt of a 14-year-old, who was tinkering with science, he had said: 

After Dawkin's recent foot-in-mouth comment on Twitter, he has drawn flak from Twitter users such as Karin Robinson, Associate Director of Ogilvy One Worldwide, trolls, etc.

The scientist who calls himself an atheist also said that had Mohammed been a white boy he would have been equally critical of him calling the reassembling of a clock as invention.

According to Dawkins, the issue is not that the child was wrongly persecuted because of his racial profile but that he called the clock an "invention" of his.
