A robber made off with about $14,000 from a Washington self-service gasoline station yesterday after he set a gasoline fire in the money window of the attendant's booth, D.C. police reported.

They said the frightened attendant fled the booth of the Amoco station at 45 Florida Ave. NE as flames and smoke began swirling inside. The robber then entered the booth through a door the attendant had left open, scooped up the cash and fled.

Police and fire department spokesmen said the man approached the money window about 11:30 a.m. and told the attendant that he wanted to buy a quart of oil. The woman told him the price and pushed out the money drawer, but instead of placing cash in it, the man poured in some gasoline and set it afire.

The man then pushed the drawer about halfway into the booth and placed a two-gallon gasoline can next to the flames on a ledge outside the half-inch-thick, bulletproof window, authorities said. With smoke accumulating inside and flames lapping around the window and gasoline can, the woman ran from the booth, and the man rushed inside.

Police said the woman, who was not further identified, was not injured in the incident. No arrest had been made in the robbery as of last night.
