A court's heard a teenage boy took part in an unprovoked attack which saw three people gang up on one man at a party.
The boy, who can't be named because of his age, appeared before High Bailiff Jayne Hughes at Douglas Courthouse.
He denied assault causing actual bodily harm and stealing a mobile phone in Mona Drive in Douglas on January 2.
Prosecutor Hazel Caroon told the hearing the incident took place shortly after 11pm when a woman at the party phoned the boy and two of his friends.
They went to the house and are said to have subjected their victim to a flurry of kicks and blows, which was recorded and uploaded to Snapchat.
Mrs Hughes remanded the boy in custody and he'll appear in court again on July 20.
