A cyclist opened fire on a man seated in a parked car in San Francisco this weekend, causing a chain reaction of destruction and injury.

Police say that it all began at 8:50 p.m. Saturday, as a 26-year-old man sat in a car parked in a lot on the 700 block of Fulton Street, which is between Webster and Laguna Streets.

Suddenly, according to the San Francisco Police Department a man in his late 20s approached the vehicle while riding a bicycle.

The cyclist, police say, shot at the motorist and grazed him. The driver, attempting to escape the gunman, took off. But his flight was short-lived, as police say that he collided with another vehicle at Fell and Webster Streets.

Fortunately, according to the SFPD, "no one was seriously injured" in the wreck, and the grazed driver was transported to San Francisco General Hospital in stable condition.

During the fray, police say, the shooter was able to evade capture, as he "fled on his bicycle in an unknown direction." As of Tuesday morning, he had not been caught, and no arrests have been made in this case.
