SAN FRANCISCO — Two pedestrians reported being hit by blow gun darts Friday afternoon on the Golden Gate Bridge, authorities said.

A man said he was walking northbound on the east sidewalk when he was struck in the thigh by a long metal dart, which penetrated his jeans and skin by about 1 to 2 inches, according to the CHP. The pedestrian flagged down a California Highway Patrol officer about 2:45 p.m. in the Golden Gate Bridge Vista Point parking lot to report the injury.

While officers were speaking with the first victim, a second person approached the group and said that she had also been hit by a dart. She said she was also traveling north on the east sidewalk when a dart struck her kneecap.

Paramedics evaluated both victims and they were released.

Both darts were collected as evidence and will be tested to see if they were coated in any chemicals. Investigators were working to acquire possible video footage of the crime.

Police encourage anyone with information to call 415-924-1100.
