In a repeat of Friday's incident at outgoing Parliamentary Affairs minister Mohammad Azam Khan's office in Lucknow, some documents and files were allegedly destroyed on Saturday at the Uttar Pradesh State Industrial Development Corporation regional office here after which the authorities sealed the premises. Several BSP workers staged a protest outside the office at Lakhanpur on hearing that some people were ''tearing and burning'' papers, prompting a team of administrative and police officials led by Superintendent of Police (Rural) Dinesh Chand to rush there.
