One Cafe owner said he ran inside his shop and locked the door after spotting a man "waving around what looked like a huge machete".
The owner told the YEP: "It was all rather scary.
"I heard a commotion and went to see what happened, then saw a guy waving around what looked like a huge machete.
"I ran into my shop, locked the door & then fairly soon after I saw armed police running around clearly looking for the guy."
The owner said other shops near the incident also closed their doors as police hunted for the suspects.
