Ahmednagar, May 16 (PTI) : Social activist Anna Hazare's office on Sunday received a letter threatening to kill him for stoking "unrest" in society, his aide said.

"The handwritten letter in Marathi was received at Hazare's office in Ralegan Siddhi village in the afternoon," said his spokesperson Shyam Asawa.

When asked about the content of the letter, he said it reads: "Tumhi samajat asantosh pasravat ahat mhanun tumhala udvave lagel (You will be eliminated as you are spreading unrest in society)".

The name of the sender on the letter is 'Ambadas Lashkare' from Nevase, 65 km away from here.

When contacted, Parner police said they have received the information about the receipt of such letter, but refused to elaborate on investigation.

Hazare had previously received anonymous threat letters. Latest of them was in January that threatened to kill him on January 26.

"Police have not traced the senders of these letters so far," Asawa told PTI.

Hazare's personal assistant Shyam Pathade had then said that the Gandhian does not fall prey to such threats.

Hazare has been given 'Z' category security cover.
