A robber in a hurry struck at three banks along a stretch of Kings Highway in Brooklyn in a span of about 30 minutes on Friday afternoon, the police said.

In the first and third robberies, tellers handed over cash to the robber, the police said, but he left empty-handed in the second encounter.

The police do not believe that the man displayed a weapon, though they were still gathering information late Friday afternoon.

The mini-crime wave began at around 2:15 p.m., when the robber entered a branch of the Apple Bank at 1321 Kings Highway. He handed a teller a note, was given some money and left, the police said.

About 15 minutes later, the man walked into a Capital One branch at 1226 Kings Highway, the police said, and handed over a note, but did not get any cash.

About 2:40 p.m., the suspect entered an HSBC bank branch at 1621 Kings Highway. Again, a note was handed over and he obtained some money, the police said.

The robber’s spree shows “a certain amount of perseverance,” said Thomas W. McKenna, a retired first-grade detective with the New York police.

“It’s very unusual for a guy to do three banks in a row, that close together, and to stay in the same area.”

Mr. McKenna added: “He’s looking for a score, there’s no doubt about that. And he’s nonsectarian about which bank he goes to. “Any bank is open play for him.”

The robber was described as Hispanic, about 5-foot-7, and 150 pounds. He wore black pants, a red shirt and a red baseball hat.

Bill Giannopoulos, owner of Madison Florist and Decorators, across Kings Highway from the Apple Bank branch, said he did not realize anything was happening until the street was swarming with police officers and a helicopter was circling overhead.

“It’s scary,” he said. “I don’t know what’s happening in the neighborhood.”

【新闻快讯】近日美国纽约市一名劫匪在30分钟内抢劫了当地3家银行，所获现金不详，虽然警方出动了直升机搜寻，但到目前为止，仍未将其捉拿归案。

据报道，这名男子在下午2:15首先通过出示要钱便条的方式打劫了纽约市的第一家银行，所获现金暂不清楚。15分钟后，他又来到第二家目标银行，却遭到失败，之后迅速逃走。然而，他并未就此收手，在2:40时又跑到附近的一家银行进行抢劫，30分钟内接连抢劫了3家银行，效率之高令人惊讶。

之后，当地警方出动直升机对其进行抓捕，却未将其捉住。据悉，这名劫匪可能是一名西班牙裔男子，身高约为1.73米，体重约为68公斤。

纽约警署已退休的一级侦探托马斯·W·麦肯纳说，这名抢劫犯的疯狂行为很不寻常，他可能只是想创造个记录，并不在乎抢劫哪家银行，“任何银行对他都是掌中玩物。”
