H’ween hellion busted in bank-rob spree

A Halloweenloving bank bandit just got a new costume — a jailhouse jumpsuit.

A terrifying robber dressed in a red skeleton mask and black gloves burst into a Brooklyn bank branch Wednesday and barked, “Happy fking Halloween!” before pulling a gun on the teller.

The thief, later identified by police as Kevin Crawford, 20, allegedly spooked teller Maria Masallo with demands for twentydollar bills.

“I told you fking 20s. Hurry up,” he allegedly yelled.

Several witnesses followed the masked robber when he fled, surrounding the thug while they called the cops. He was busted nearby by Borough Park Shomrim volunteers, who heldd him until the police arrived.

Crawford was at the end of a two-day bank-robbing bender when hehe was apprehended, according to police sources.

On Tuesday, he allegedly struck at the Dime Savings Bank in Williamsburg, where he tried to open an account with a check written out for only 17 cents. When a teller denied the request, he became livid and stormed off — only to return later.

The threatening youth allegedly gave a different teller a note: “Give me the money out of the reregister. I will kill you bitch.” Crawford allegedly fled the bank with a loot bag containing $1,960. On Wednesday afternoon, the brazen robber got in the Halloween spirit early when he allegedly hit up the Emigrant Savings Bank on Myrtle Avenue in Fort Greene.

“Trick or treat, give up the cash or I will kill you, bitch motherfker,” he allegedly snarled at the teller.

When the teller did not immediately empty out her drawers of cash — but instead turned to speak with her boss — the robber panicked and fled emptyhanded.

The bank employee, Wilhelima Burgher, called 911, but Crawford pulled a disappearing act until later in the day.
