Maharashtra Navnirman Sena chief Raj Thackeray has received a fresh death threat, this time in the form of a letter, from the Sarvodaya Samaj in Bihar. Written and signed by Ashok Kumar Singh, who claims to be the founder president of the Samaj, the letter states that ‘five revolutionaries of the Samaj have decided that one of them will kill Thackeray before December 25.’
