Newly released surveillance footage shows the moment that a man collapsed after he was slashed with a machete in Los Angeles, Calif.

The 43-year-old victim was riding his bike when he was attacked early Sunday morning.

Police say the four men tried to pull the victim off his bike, and when he resisted, one suspect slashed him with a 24-inch machete.

The victim’s left thumb was sliced off, his skull was fractured, and he sustained cuts to his arms and legs.

The four suspects fled empty-handed and remain at large.
