“ The grand jury knew petitioner had assaulted a man with tire irons because petitioner himself told them so. The tire irons were the 'evidence' which according to the police officer petitioner had tried to bribe him 'to get rid of.'

“ He then testified to the assault which he had perpetrated by the use of tire irons. Four days later a police officer testified before the grand jury that after a chase, he had arrested petitioner and another, and thereupon had taken the tire irons from them. The officer also testified that following petitioner's arrest petitioner had offered the officer a bribe to change his testimony. Petitioner was subsequently indicted by the grand jury for bribery, and, following an unsuccessful motion to dismiss based on the grant of immunity, he pleaded guilty to attempted bribery. ”
