The father of one of the teens involved in the trashing of wreaths at a Melbourne war memorial has said he is “ashamed”.

The teens have received a barrage of abuse on social media since a video of them defiling 50 wreaths laid by school students went viral.

The incident occurred around 6pm Sunday night at Box Hill Gardens, in the city’s east.

Four teenagers filmed themselves stealing wreaths, wearing them on their heads and throwing them around the parkland.

“The boys are bringing us flowers,” one girl laughs.

“That’s so sweet, I love you.”

Box Hill RSL said the actions were disgraceful ahead of Anzac Day tomorrow.

“It sends a bad message,” member John Haward said.

“It’s the significance of what they’ve done to desecrate the wreaths laid by school children, some the same age.”

Council workers spent hours cleaning up the mess and trying to salvage as many wreaths as possible.

“It’s disgusting, the park man has worked here 17 years and says he has never seen anything like that,” one nearby resident said.

The teens – who 9NEWS has chosen not to identify – do not appear to be remorseful, taking to Facebook to tell critics to “get over it”.

“No one’s business what we do,” she wrote.

“I’m gunna start hitting snitches.”

But the father of one of the teenagers, who requested not to be identify, said no disrespect was intended.

“I am saying that they are ashamed, and embarrassed of the dishonour and disrespect they all showed to our country’s greatest heroes, both past and present,” he said.

“They admit, they just weren’t thinking at all, just out having fun and trying to impress each other.

“As a parent, I have to say I am ashamed, embarrassed and angry at their life decisions of late and especially the disrespect and dishonour they showed on Sunday.”

Police have not laid any charges.
