Richmond firefighters and police responded to Byrd Park on Tuesday morning after a man suffered a medical emergency and drove off the edge of Fountain Lake.
Police said officers responded at 8:33 a.m. to a report of a vehicle in the lake. They arrived to find the driver suffering from what was described as seizures.
A sergeant and a patrol officer helped the man out of the car, which was hanging sideways over the edge of the lake with the passenger side submerged.
The driver was taken to a local hospital, and no one else was injured.
