KARACHI - A telephone call about the installation of a bomb created panic in a privet school within jurisdiction of North Nazimabad Police Station. The panicked students and management evacuated the premises causing postponement of the examination scheduled to be held on Monday. As per details an unknown parson told the school management about the presence of a bomb at the campus. DSP Khawaja Shehram told the media representative that the caller threatened that a bomb had been planted in the school. Just after the report of the incident, a bomb disposal squad reached and searched through the school. The hoax was made through a mobile phone to an official at the school on his landline official phone, who intimated the police immediately. The police officials believed that it might have been a 'conspiracy' of any student intending the postponement of the examination to be held on the same day.
