Mahendra Singh Dhoni has been provided with extra security after reportedly receiving an extortion letter demanding Rs50 lakh (US$ 103,091). News reports say his security has been upgraded to ‘Z’ category – the highest level in India - and he has a 45-strong team protecting him. Police officials said Dhoni's family received the extortion letter on Monday. Earlier this month, Dhoni travelled unescorted to the Ranchi airport after seemingly being unsatisfied with the level of security given to him. He also applied for a licence for a .9mm pistol.
