Armed police, as well as members of the armed offenders squad attended a suspected firearms incident in Hamilton St, East Gore, just after 2.30pm — which turned out to be a dud.
In a statement, police said officers had made inquiries and were satisfied no-one was at risk. No-one was injured and no arrests were made.
A person inside the Longford Tavern at 29 Hamilton St confirmed they had been in lockdown, but declined to give their name or any other details about the situation.
Hamilton St resident Patricia Johnston said she watched from her home as the armed offenders squad drove up the street.
"I was sitting here watching TV and next thing I saw a police car go past with policemen sitting in the back with guns.
"It was quite a fright seeing that go past."
Police said inquiries were continuing.
