“I watched a guy in [the store] talking to staff near the entrance, then he went to leave and pick up a blanket sitting near the front. Then I heard shouting and it really freaked me out,” he said.
The man “surrendered straight away”, Jason said, while five more armed officers came to the scene.
He did not see the man carrying any weapons and said “everything was calm inside the shop”. Jason said he was “trapped” in the lockdown for about 25 minutes.
Police said there are no reports of injuries. They remained in the area to reassure retailers.
In September last year, Islamic State supporter Ahamed Aathil Mohamed Samsudeen stabbed and wounded several shoppers during a terror attack at the Countdown supermarket at LynnMall before being shot dead by members of the police Special Tactics Group.
