A robber who rated bank tellers on their appearance and courtesy and handed them notes that demanded cash and quoted the Bible, held up two District Banks and attempted to rob a third yesterday.

The robber, who referred to himself in the notes as "the king" had not been apprehended as of late yesterday, police said. No one was injured in any of the robberies.

Police concluded that the same man had been involved in all three cases because of the matching descriptions. The notes quoted generally from the Bible, and other notes -- some written during the holdups -- rated tellers on appearance and manner.

In a fourth and apparently unrelated bank robbery, a man held up the Union First National Bank of Washington at 1011 Connecticut Ave. NW at 1:46 p.m. yesterday. When he stopped outside the Farragut North Metro station, apparently to check his take, the money bag he was carrying exploded, covering him in red dye and startling midday shoppers and Metrorail riders.

Though police quickly coverged on the scene, the man escaped, police said.

The series of bank robberies yesterday began at 9:15 a.m., when the Bible-quoting robber entered the Industrial Bank of Washington at 125 45th St. NE. He handed a teller a note, but when she refused to give him any money, the man fled, according to Sgt. Edward Dory, head of the D.C. police bank squad.

About 1 1/2 hours later, apparently the same man robbed the Riggs National Bank at 4249 Wisconsin Ave. NW.

At 1:45 p.m., the American Security Bank at 401 M St. SW was robbed -- apparently by the same man -- who again handed a teller a note demanding cash. He fled with an undisclosed amount, police said.

One minute after the Americans Security robbery, Dory said, the Union First was robbed. Because of the distance between the two banks, Dory said police were discounting the possibility that the robberies were made by the same man.
