Police in pursuit of an Outer Sunset vandal arrested a man Tuesday morning for the crime, and reported that he was also in possession of a switchblade and some fireworks.

San Francisco Police Department spokesperson officer Robert Rueca says that at 1:17 a.m. Tuesday, police were called to the 1700 block of 42nd Avenue, which is between Moraga and Noriega Streets on reports of a vandalism in progress.

When police arrived, Rueca say they discovered "a suspect on the block matching the description" of the vandal. He was taken into custody at the scene.

Rueca says that the suspect, a 31-year-old man who Rueca says also had an outstanding arrest warrant, was also carrying a switch blade and "consumer fireworks."

An initial SFPD report described the items as "Barrel Bombs," a term most commonly used to describe cylindrical explosive devices made from a barrel and containing shrapnel. In a call to SFist Tuesday morning, Rueca says that that term was used by police in error, and that the suspect "only had the kind [of fireworks} you put on the ground and then they sparkle."
