Radhakrishnan Thankappan Nair sustained injuries in his hand and shoulder and is being kept in the intensive care unit of the Salmaniya Medical Complex in Bahrain's capital, Manama, the Gulf Daily News reported Monday.

According to the report, when Nair, hailing from Thiruvananthapuram in India's Kerala state, went to get his passport ahead of a planned holiday, his employer allegedly told him that he would get it only if he signed a blank document.
