Andrew Lundy from Ross Houses in the Mount Vernon estate appeared at Belfast Magistrate's Court accused of riotous assembly and attempting to cause grievous bodily harm to police officers who had stopped an Orange Order parade passing the Ardoyne area.
In total, 53 people have now been charged and 81 arrested in connection with disturbances the broke out during and after the march.
A prosecution lawyer on Thursday said that Lundy was seen climbing on top of a landrover and hitting out at police shields and throwing boulders and masonry at PSNI lines.
A police witness said up to 5,000 people were on the Woodvale Road and there was a heavy and sustained attack on police.
She said Lundy had been identified from CCTV footage and that he was involved in the trouble for over two hours.
After he was arrested, Lundy admitted he took part in the attacks, adding that it "felt like a bit of fun and that others were doing it".
The police witness objected to bail because of continuing tensions in the area and because Lundy had shown no remorse.
However a defence lawyer said Lundy had said he was sorry and that he had been stupid.
Refusing bail, District Judge Austin Kennedy said Lundy had shown a shocking attitude, adding: "The defendant said it was a bit of a laugh but the lives of police officers were put at risk".
He remanded Lundy in custody until 22 August.
At the same court, a 16-year-old youth wept uncontrollably as he appeared on a riotous assembly charge. The teenager, who can't be named for legal reasons, was said to have been seen throwing a number of missiles including fireworks and beer bottles at police on the Woodvale Road on the Twelfth.
He was remanded in custody to appear at a youth court on Monday.
