A 39-year-old cyclist who allegedly smashed a Zipcar with his bike lock during a late August Critical Mass event has been arrested and is expected to be arraigned Wednesday, say officials.

Ian Hespelt, a 39-year-old San Francisco resident, was arrested Sunday in Mission Bay and booked on a series of charges, including false imprisonment, assault with a deadly weapon, vandalism and throwing a substance at a vehicle.

The arrest came after Hespelt was caught on video allegedly striking a car with his bike lock on Aug. 28, say police.

The incident occurred in the Marina a block away from the Palace of Fine Arts when a stream of cyclists converged with traffic.

The video shows Hespelt laying down his bike in front of the Zipcar, which appeared to be attempting to make its way through the bicyclists. After Hespelt and other cyclists surround the car, it maneuvers away but is then stopped again.

When the car pushes past the cyclists, Hesplet strikes the car several times with his U-lock as it drives away.

Police say $2,000 worth of damage was done to the car.

Critical Mass is a two-decade-old monthly event that falls on the last Friday of the month in which cyclists take over what is usually car-filled streets. The event is not without its controversy and confrontation, often with irate drivers who have been stalled in traffic.
