Irish Rail is investigating how CCTV footage of an alleged attack at Howth Junction DART Station was leaked to the public - and subsequently social media.
It's reported that the matter has also been referred to the Data Protection Commissioner.
Mairead Clearly reports:
"During the incident last month, a young woman fell between a stopped train and the platform, needing assistance from staff members.
The footage was captured on CCTV on April 1st and appeared on social media - causing widespread anger.
Now, Irish Rail is investigating how videos of the incident was leaked, according to the Irish Times.
It told the paper that customers expect the station CCTV to be used for their safety and security - and 'not to be distributed in an unauthorised manner'.
Three juveniles - one aged 13 and two aged 16 - were arrested in connection to the incident last week. "
