Now, months after being praised as a hero, the 44-year-old is facing criminal charges.
According to police, an investigation was launched following allegations involving a domestic dispute at a home in Bankstown, a suburb in western Sydney.
Authorities allege that Al Ahmed placed his father in a headlock during the incident.
New South Wales Police confirmed that officers from Bankstown Police Area Command began investigating the matter before issuing charges.
In a statement, police said a 44-year-old man was served with a Court Attendance Notice for common assault involving domestic violence as well as a charge of stalking or intimidating another person with intent to cause fear of physical or mental harm.
Police have also obtained an Apprehended Violence Order (AVO) to protect Al Ahmed’s father.
The case is scheduled to be heard at Bankstown Local Court on July 29.
Al Ahmed has strongly denied the allegations.
Speaking to ABC, he described the claims as false and said he had no knowledge of the alleged incident.
“It’s fake information … it’s not true at all,” he said.
“I don’t have any information at all.”
The charges have attracted attention because of Al Ahmed’s widely publicized actions during the December attack that shocked Australia.
On December 14, a gunman opened fire on people attending a Hanukkah celebration near Bondi Beach. Chaos erupted as families, children, and community members attempted to flee the scene.
During the attack, Al Ahmed, a Syrian-American living in Australia, intervened and confronted the shooter.
Videos recorded by bystanders quickly spread across social media, showing him tackling and disarming the gunman despite the danger to his own life.
The footage earned widespread praise, with many describing him as a hero whose actions may have prevented additional deaths and injuries.
In the process of confronting the attacker, Al Ahmed suffered serious injuries.
He was shot twice and later underwent surgery while doctors worked to stabilize his condition.
As news of his bravery spread, support poured in from around the world.
Social media personality Zachery Dereniowski helped organize a fundraising campaign through GoFundMe to assist Al Ahmed during his recovery and to recognize his actions during the attack.
The campaign generated significant attention and raised millions of dollars.
In one widely shared moment, Dereniowski visited Al Ahmed in the hospital and surprised him with a symbolic check representing more than $2.5 million in donations contributed by supporters.
Speaking from his hospital bed at the time, Al Ahmed said he acted instinctively because he could not stand by while innocent people were being attacked.
“When I do save the people, I do it from the heart because it was a nice day, everyone was enjoying, celebrating with their kids,” he said.
“Woman, man, teenager, all of this, everyone was happy and they deserve to enjoy and it’s their right.”
He also expressed his appreciation for Australia and spoke about the importance of standing up against violence.
“This country, best country in the world, but we’re not going to stand and keep watching, enough is enough,” he added.
The new charges do not relate to the Bondi Beach attack or Al Ahmed’s actions during that incident.
As with any criminal matter, the allegations remain before the courts, and Al Ahmed is presumed innocent unless proven guilty.
The case is expected to receive significant public attention given his high profile following the December tragedy and the widespread recognition he received for his actions that day.
For now, Al Ahmed continues to deny any wrongdoing as he prepares to face the allegations in court later this summer.
