Police in New York City have arrested a teen for allegedly beating a 60-year-old man to death on Christmas Eve – and it was all caught on camera.

According to police, the video shows the assault of Juan Fresnada in the Bronx. Fresnada was with 29-year-old acquaintance Byron Caceres when investigators say several men confronted them. One of the attackers is seen throwing a victim to the ground and proceeding to attack.

Police say Fresnada suffered bleeding in the brain. He died Friday. Caceres says Fresnada suffered the fatal blows while trying to spare him and urging him to run to safety, which he did.

Abu Conteh, 18, has been charged with murder and gang assault. Police say the men robbed them, but only ended up with $1.

Caceres refused medical treatment.
