A sick Snapchat video shows a teenage boy being threatened by a gang before being pushed to the ground in a shocking attack.
The heartless group of thugs ganged up on the young man in an attempt to humiliate him.
The incident happened in Rush, north county Dublin, on Saturday and concerned parents say they'll be handing the footage over to gardai.
In the video, multiple youths are seen holding their phones up to the young teen with one saying "get on your knees before I hit you", Dublin Live reports.
The lone boy bravely stands his ground as the bullies begin to surround him.
The boy asks them to stop recording but they refuse and push him to the ground.

The video then cuts out and it is not clear what happened afterwards.
The attack is one of a number across Dublin that has been uploaded to social media in recent months.
Many parents have previously told Dublin Live that their kids are too afraid to tell them what's happening, and that they've struggled to collect proof as apps such as Snapchat automatically delete the videos after 24 hours.
The popular app also notifies the video owner if someone takes a screenshot - meaning many are too scared to take a records of what happens as the perpetrators may then target them.

Gardai advice to anyone who wishes to report cyber-bullying to do the following
1. Keep the evidence and don't delete anything.
2. Save messages and take screenshots - if you can't take a screenshot out of fear of the person being notified, many iPhones have a screen record function.
If you turn the screen record on, then view the message/content, and then turn it off, you will then have a record in video form.
3. Report it to them. You should also consider reporting to the child protection agency Tusla.
4. Do not delete the account as the evidence will help gardai.
