"In his suicide note, Batcha said he was embarrassed by the CBI raids at his premises," a top police official said.
Batcha, found hanging at his house today and declared brought dead at a private hospital, blamed none for his suicide and he felt sorry for Raja's plight, the official said.
In the note, he was also peeved at the extensive media coverage to the CBI raids when sleuths raided his premises in Chennai and native Permbalur, they said.
In the long letter, which started with an apology, he expressed his wish to be reborn and wanted his siblings to be happy and his wife and children to stay in Chennai for their education.
Meanwhile, the police filed an FIR for a case of suicide, following a complaint by Batcha's wife Banu. Police said she had alleged that her deceased husband could not cope with the 2G spectrum probe.
