Police are investigating whether the same woman tried to rob two Oahu banks this week.

At about 3 p.m. Wednesday a woman walked into the Ala Moana Center branch of Territorial Savings Bank and tried to enter an area restricted to tellers, police said. She demanded money and said she had a weapon, but left when a bank employee confronted her.

The woman is described as in her 20s, about 5 feet 4 inches tall and about 130 pounds. She has brown eyes and wore a gray jacket, gray pants, dark gloves and a black nylon net on her hair.

The day before, at about 12:55 p.m., a woman walked into the Wahiawa branch of First Hawaiian Bank, approached a teller, said she had a weapon and demanded money, police said. She left the California Avenue bank when the bank manager asked her to leave.

Police did not offer a detailed description of the woman in the second case. But Sgt. Kim Buffett of Crime­Stop­pers said the woman has "the same description" as the suspect in the first case.

Police are looking at the possibility that the same woman committed both crimes, Buffett said. In neither case did the woman leave with any cash, she said.

Anyone with information on either incident or both incidents is asked to call Crime­Stop­pers at 955-8300, or *CRIME on a cellphone.
