NEW YORK (Reuters) - A lawyer for former Tyco International Ltd. chairman Dennis Kozlowski on Friday requested to seal videotapes of a raucous $2 million party on Sardinia to ensure that potential jurors don't see footage before Kozlowski's criminal trial begins later this month. The issue surfaced during a pretrial hearing on Friday in Manhattan Supreme Court. Kozlowski's defence also wants to prevent prosecutors from introducing prior bad acts allegedly committed by Kozlowski. Jury selection for the trial is expected to begin September 29. Kozlowski and Mark Swartz, Tyco's ex-finance chief, have pleaded not guilty to charges they looted Tyco out of $600 million through unauthorised pay and fraudulent stock sales. Tyco accuses Kozlowski of recklessly tapping company funds for his lavish lifestyle, including using company money for his second wife's 40th birthday party in Sardinia.
