Several vehicles, including buses and even three bicyclists, went past on a Miami street as a naked man chewed the face off a homeless man Saturday in what has been called a zombie-like attack.

The attacker then spends several minutes crouched over the victim, including when a bicyclist rolls by on the sidewalk and a white sedan rolls very slowly past the scene.

"When the officer approached him, told him to stop, pointed a gun at him, he turned around and growled like a wild animal and kept eating at the man's face," Aguilar was quoted as saying by WPLG.

Augilar said he suspects that the attacker was under the influence of "bath salts," a drug that contains synthetic stimulants that can "cause chest pains, increased blood pressure, increased heart rate, agitation, hallucinations, extreme paranoia, and delusions," according to the National Institute of Drug Abuse.

Four other instances of drug use in Miami-Dade bear resemblances to Saturday's attack, Aguilar told WPLG.
