Vienna police dispatched officers to 138 Patrick St., S.E., on May 20 at 4:54 p.m. after receiving a report of a single-vehicle accident.
Police located the driver of the vehicle that struck a building, and during interaction with him detected signs of impairment, police said.
After the driver failed a series of field-sobriety tests, police arrested the driver for driving under the influence and had the 20-year-old Vienna man take an official breath test.
While police were performing the test, the man suffered a medical emergency and had to be taken to the hospital, police said.
Police obtained a search warrant for the driver’s blood and released him on a summons.
