PARTY-GOERS have been left shaken after a gunman terrorised a 21st birthday celebration at an Ipswich bowls club.
What began as a night of fun quickly turned into a night of terror, when the male gunman burst through the doors of the Goodna Bowls Club at 9.50pm on Saturday night and demanded cash.
Witnesses said the man, armed with a shotgun and with his face covered, threatened staff and patrons for cash.
About 35 guests had attended the party, including a 94-year-old relative of the birthday boy.
During the robbery, two patrons received head injuries and were later treated by Queensland Ambulance Service crews.
The man allegedly stole money from the venue's cash registers before he fled on foot.
Patrons and staff were asked to remain at the scene to assist police with their inquiries.
Club treasurer Cathie Wilmington said that at first partygoers and staff thought the robbery was a joke.
"When the man barged through the doors and began shouting, we thought it was someone playing a prank on the birthday boy," she said.
"But it soon became obvious that this was no joke.
"It was definitely a birthday party we all won't soon forget.
"When the gunman left, a lot of people were shaken by the incident.
"One gentleman was hit in the face with the barrel of the shotgun."
Police are investigating if the incident is linked to a robbery attempt that took place less than 2km away at a bottle shop on Queen St.
A man with a similar description and also armed with a shotgun, attempted to gain entry to the business at about 9.40pm but fled without success.
During the incident, the man threatened a staff member and a member of the public.
Police have asked for anyone with information to phone Crime Stoppers anonymously on 1800 333 000.
