Security concerns prompted the police to ask Entrepreneur Development Minister Mohd Nazri Aziz to cancel the debate with a PAS leader in Terengganu last night, said the minister's press secretary Mohammad Isa today.

"The minister was able to go into the hall and up the stage in order to explain the change of plans. Understandably, the audience was disappointed," he added when contacted.

According to Mohammad, several police personnel escorted Nazri out of the Islamic Administrative Centre hall - the venue - for the debate.
