Singh missed the easy but crucial chance in the closing stages of the arch rivals' dramatic Asia Cup clash on Sunday night won by Pakistan in Dubai in the final over â€” when the 23-year-old was the bowler.
Singh's Wikipedia entry was briefly altered to link him to the Khalistan Sikh separatist movement, reportedly prompting the government to summon executives from the open-edit online encyclopedia.
"He is a Khalistani and has secret ties with Pakistan," said one Twitter user. "Arshdeep Singh has taken money as a Khalistani agent," wrote another.
After the match, star Indian player Virat Kohli backed Singh, saying that "anyone can make a mistake." The hashtag #IndiaWithArshdeep, supporting the young player, was trending on Twitter.
It is not the first time that cricketers from Hindu-majority India's religious minorities have faced such attacks.
Last year Muslim player Mohammed Shami became a target of abuse after India were thrashed by Pakistan in the T20 World Cup.
Thousands of hate messages flooded social media, including Shami's Instagram account, calling him a traitor and alleging he had taken money to throw the game.
Kohli, at the time India captain, also vigorously backed Shami, saying: "Attacking someone over their religion is the most pathetic thing that a human being can do."
The Super Four match on Sunday was the second time India and Pakistan have played against each other in the ongoing Asia Cup. India won the first game and they may meet again in the final on Sunday.
