“It was a person that went up to receive Communion at the 5 p.m Mass and then didn’t consume the consecrated host,” Marlow said. “He left without consuming.”

“There was a visiting person [also in attendance] who stood up and confronted the person and told him, ‘You can’t leave the church without consuming the host,’” Marlow said. “And the guy went off and punched him and ran out of the church.” 

“The gentleman who got punched, I was told, was not in serious condition,” Marlow added. “He just took a punch and was treated by the paramedics.”

It was unclear at press time what happened to the Host.

City Supervisor Aaron Peskin told the San Francisco Standard that police said the man “set off a pipe bomb” during the pursuit incident before subsequently igniting a “Molotov cocktail.” There were no serious injuries, Peskin told the outlet.

The SFPOA included in its X post a photograph of an “improvised device” said to have ignited on a city sidewalk or street.
