The student was a big fan of the late Bal Thackeray. He had sent a message to Uddhav Thackeray's personal assistant saying, "Saheb, your dream will now be fulfilled, a bomb blast will occur at the 20-20 match".
But, when the student realised he had been caught out, he cooked up an abduction story, fearing arrest, police sources said.
Superintendent of police Dattatrya Mandlik told PTI that the student had come to the police station on Tuesday night and claimed to have been abducted by 4-5 persons, who forced him to call the Bangalore police on Monday night.
When quizzed, he admitted to having phoned the Bangalore police himself, threatening a blast, Mandlik said, adding that security had to be beefed up at the Bangalore stadium.
Inspector Syyad Jilani Kadar said the student was booked under various sections of the Indian Penal Code.
