RTE is again under fire, this time for showing a bloody and brutal dog fight in the latest episode of 'Love/Hate'.
Campaigners say they are being "tormented" by scenes in the latest series which portrays violence towards animals.
The first episode of series four sparked dozens of complaints as it showed a cat being machine-gunned on an estate.
Now the fourth episode has been criticised for featuring two chained dogs covered in blood and cheered on to attack one another. The Animal Rights Action Network (ARAN), which campaigns against animal cruelty, was notified about the scene over a week ago.
"We were told to brace ourselves," ARAN director John Carmody told the Irish Independent.
Mr Carmody said they now feared an increase in the illegal sport.
"Frankly, we're tormented with this production at the minute. They're bulling for ratings and we wish them luck, but they're putting the wrong ideas into people's heads.
"The fact of the matter is, some viewers will come away from watching that thinking dog fighting is cool."
RTE informed the Irish Independent that it could not register any complaints from Sunday's programme until later today.
However, one concerned viewer called the station yesterday about a later scene in the episode, which appeared to show Fran (actor Peter Coonan) urinating on a grave.
The woman, who wished to remain anonymous, told this newspaper that she was "utterly disgusted and very upset", as she believed the scene was filmed near her own mother's grave.
The episode was shot last April, in Deansgrange cemetery, Co Dublin.
