Gardaí are appealing for witnesses over a 'racially motivated incident' at Dublin's Royal Canal.
They say a young woman was racially abused by a number of youths on the side of the canal, and was then pushed in.
It comes after footage emerged of the incident on social media.
The footage was originally uploaded on TikTok, but has also been posted to Twitter.
It shows the woman telling the young boys: "Tell your friends don't racially discriminate, because that's criminal".
Some of the boys then proceed to push the woman into the canal.
She shouts out while being pushed, as the boys laugh.
An Garda Síochána says it is appealing for witnesses over the 'racially motivated incident'.
It happened between Lock 11 and 12 of the canal at around 7:25pm on Friday.
They are appealing for witnesses and are asking that anyone with information in relation to this incident to make contact - in particular anyone who may have mobile phone footage or a voice recording of the incident.
Anyone with information can contact Finglas Garda station on 01-666-7500, the Garda Confidential Line at 1800-666-111, or any Garda station.
In a tweet earlier, Dublin Lord Mayor Hazel Chu said: "My heart goes out to the assaulted woman Shirley Xuedan Xiong. Make no mistake this was an assault".
She also said she will be contacting Garda Commissioner Drew Harris this week, and added: "This is far from the first assault case on the canal stretches. Let's work to making it the last."
