A robber hit two Houston area banks within an hour Monday afternoon, leaving in a taxi each time, authorities said.

The robber got no cash in either holdup, FBI officials said. FBI officials said a woman entered a Bank of America at 2302 Fannin in Midtown about 3:15 p.m. and handed a note to a teller demanding cash. About 3:35 p.m., the same woman went into the Bank of America at 1905 W. Gray, near Dunlavy, and again handed a teller a note demanding cash.
