Stating that there was no place for such intolerance in a democracy, he said that the Trump government should take stringent steps to check such incidents.
"Shocked as another Sikh abused in the US, no place for such intolerance in a democracy...," Mr Singh said in a series of tweet.
In another tweet, he said: "Indians, Sikhs in US are not feeling safe" and asked Prime Minister Narendra Modi to take up their security with the US President Donald Trump.
Later in a statement, the Chief Minister said that the governments in both the US and India needed to address the issue urgently.
Urging the central government to discuss the matter of security of Indians, and Sikhs in particular, with the US government, Mr Singh said the two countries needed to collaborate to ensure the safety of the Indians through all possible measures.
"With many of the racist attacks traced to mistaken identity, as a result of Sikhs being taken to be Muslim fundamentalists, it is important that awareness about Sikh identity be created among the Americans by the Trump government," he added.
The Chief Minister called upon the US President to be sensitive to the concerns of India in this matter as the two countries were the world's leading democracies, which needed to work together to promote the value of equality and tolerance.
