Some Northern Ireland Railways services between Bangor and Portadown were cancelled earlier today due to “disruptive passengers”.
Translink made the announcement on Twitter saying: "Due to disruptive passengers the 11:55 #Bangor to #Portadown was terminated at Lisburn. It will no longer call at Moira, Lurgan and Portadown. Sorry for any inconvenience."
Also a result the 13:45 Portadown to Bangor train service was also cancelled.
A Translink spokesperson told Belfast Live: "A passenger on board the 11.55am Bangor to Portadown train became aggressive towards other passengers and towards the conductor when he intervened.
"The train was terminated at Lisburn and the PSNI was called for support.
"We view this behaviour as entirely unacceptable and we apologise to those passengers whose journey was disrupted.
