SAN FRANCISCO (KRON)–A threatening letter is circulating around San Francisco’s Mission District, targeting the homeless community.

KRON4’s Hermela Aregawi spoke to neighbors in the area to find out who may have written the letter that was posted at a skate park.

The letter is littered with threats to hurt the homeless people in the park and beat them silly.

Part of the letter reads, ” we are sick of watching you leave needles in the park and stealing.”

One man says he saw the culprit posting the flyer. He went to confront him and was pepper sprayed.WHAT OTHERS ARE CLICKING ON:
