An early-morning altercation on Mission Street took a bizarre direction, after a machete was thrown into the mix.

San Francisco Police Department spokesperson Officer Grace Gatpandan says that it was almost 2 a.m. Monday when a disagreement between to men on the 4000 block of Mission Street turned violent.

According to Gatpandan, 41-year-old SF man Amilcar Alfaro allegedly pulled a machete from a nearby white pickup truck, then struck the man with whom he'd been arguing "several times."

Gatpandan says that the motive for the attack remains under investigation.

The victim, who was also a 41-year-old SF resident, was transported to San Francisco General Hospital with injuries to his back and elbow from the attack. He is expected to survive, Gatpandan says.

Alfaro, who had allegedly fled by foot from the scene of the crime, was tracked down by SFPD and booked into county jail on suspicion of attempted murder, assault with a deadly weapon, felony threats and mayhem.
