A man has been detained by police in connection with the explosion at the Government Campus Plaza Parkade earlier this week.

The arrest was made after officers who were conducting investigations in the area of the multi-storey car park, offices and restaurants observed a man walking around the building and looking in at stores and shops.

They stopped him and proceeded to search a bag he had been carrying. The bag, they said, contained items that looked similar to parts of an explosive device, which was set off at the Parkade on Tuesday morning.
