A man with 45 previous arrests for robbery was arrested again Friday after allegedly bicycling up to a Dunkin' Donuts drive-through window, threatening the clerk and pedaling away with a register drawer full of cash, police said.

Vernon Lewis, 42, of 6 Lincoln Terrace, then nearly collided with a police officer near City Hall who was responding to another call, police said.

After learning that the Dunkin' Donuts at 255 East Main St. had been robbed, the officer found Lewis near the public library, police said. He was carrying $321 cash, police said.

Dunkin' Donuts employees and customers identified Lewis as the alleged robber, police said.

He faces charges of first-degree robbery, second-degree larceny, second-degree threatening, interfering with police and brandishing a facsimile firearm.
