A San Jose man was brutally attacked early Wednesday morning at the laundromat where he’s worked for the past two years.

The beating was caught on surveillance video. It’s spreading quickly online, not just because of how violent it is, but because it’s raising new concerns about the dangers many overnight workers face.

Surveillance video shows a group confronting the 57-year-old worker. Without warning, one man throws a punch.

The worker grabs a broom, trying to keep the group back. Instead, he’s shoved into a door and knocked onto the ground.

Then the attack escalates.

Several people swarm the victim, kicking and punching him before taking off.

Police say it happened around 2 a.m. Wednesday. The worker suffered major head injuries but is expected to recover. Officers have arrested four people in connection with the attack.

Investigators say the group also stole some of the victim’s belongings before leaving.

The victim’s daughter identified him as 57-year-old Le. She says he’s now back home, recovering with stitches in his head.
