Police are hunting a pair of yobs who filmed themselves pushing a homeless man into a canal after pouring beer over his head.
Footage shows two cowardly thugs approaching the victim, who was slumped next to a bench, before launching the attack in Birmingham city centre.
The incident happened on a towpath near Snow Hill Train Station earlier this week.
One of the pair asks the man: "Wahgwan, you alright'?" before his laughing pal says: "What's up mate?"
They then proceed to tip a can of Stella lager over his head while saying: "Come on bro, wake up bro, wake up".
The person filming the footage then shoves the man into the canal before running away from the scene laughing.
The footage was uploaded to the website Birmz Is Grime where it has been viewed and shared thousands of times.
The video sickened social media users, with one saying: "That’s just awful, why oh why would you do something like this??"
Another person added: "Lowest of the low, attacking a clearly vulnerable man. Some people literally have nothing better to do. Shameless pair of scumbags."
Other people offered to provide food and clothing to the victim, who police have since spoken to, in a bid to help him back on his feet.
Birmz Is Grime wrote it had uploaded the video “to bring awareness to these disgusting actions that I’m sure are carried out more often than we see”.
Sergeant Dale Quiney, of Birmingham Police, said: “We’re aware of footage on social media showing a man being pushed into a canal in Birmingham.
“While it has not been reported to us, we have identified the victim and will be making contact with him to get further details.
“This is a really nasty attack on a vulnerable member of the public and I’d urge anyone who saw what happened, or who knows the names of those involved, to do the right thing and get in touch with us."
