An animal welfare group has said it is hopeful of tracing a man who can be seen on an internet website biting the head off a live pet mouse.
About 2,000 people have viewed the incident on the YouTube site.
The incident is believed to have happened at a party in the Turf Lodge area of west Belfast.
"We've had a couple of leads which my staff will be running down today," an Ulster Society for Prevention of Cruelty to Animals spokesman said.
Spokesman Stephen Philpott said: "If the USPCA in this instance can prove unnecessary suffering, which is the key phrase under the Welfare of Animal Act, we will certainly be taking it further."
Mr Philpott said the organisation had already had a "great response" from the public after appealing for help to identify the man.
The two-minute video shows the man, referred to as Johnny, drinking from a can of beer before biting the head off the mouse and chewing it, egged on by other party-goers.
He then spits it out saying it is impossible to swallow. The man is heavily built, in his 20s, with short hair.
Mr Philpott said he was worried by the trend of people being recording carrying out acts of cruelty against animals.
"We have become alarmed in the last year at how many of these incidents we have been asked to have a look at," he said.
"Unfortunately, this is like a type of happy slapping against animals where people record themselves doing depraved things and then show that footage to the rest of their colleagues."
Mr Philpott said the acts being carried out were designed to be as shocking and "grotesque" as possible.
"Singling out a defenceless animal like this just simply to glorify yourself or publicise yourself just can't be done," he said.
Now didn't THAT act take some brains and brawn...NOT. Surely he could take the "Stupidity" Award of the month, if not the year. Hope they catch the guy and sentence him to cleaning out pig sties and horse stables for 6 months.

Thank you for raising awareness on this inhuman behaviour!
Such people require love of the most vital degree; because whilst they are non-living they are a danger to every being and themselves.
Peace to everything...

Gosh!!!!!! Peter, I'm feeling sick about people's cruelties. How can anyone do this to a helpless mouse? I hope he will be found and brought to prosecution.
Very sadly, this insanely cruel and barbaric type of human behavior is on the rise - all over the world these days. There are also cat and kitten killers on the Internet trying to glorify their extremely atrocious actions. And it truly makes me wonder about the so called 'inherent goodness' of our human race.
Let your children enjoy the wonders and adventures of pets that join a family, bringing joy and heartwarming moments to their everyday lives. This story is about Tubby and Riley, two dogs who needed a good, loving home.
Yes, too many sickos in this world!
