Two days after a political corruption scandal rocked Albany, a new, unrelated bribery scheme emerged on Thursday, adorned with a can-you-top-this quality: For more than a year, a sitting state legislator wore a wire intended to catch at least one of his colleagues.

The secret recordings helped lead to the arrest of Eric A. Stevenson, a Democratic state assemblyman representing parts of the South Bronx, who was charged by federal prosecutors in Manhattan with accepting more than $22,000 in bribes to help developers open adult day care centers in his district. Mr. Stevenson was also accused of introducing legislation to block competing developers from building new centers for three years.

He seemed keenly aware of the risk of getting caught, as so many of his colleagues in Albany had been before, according to a criminal complaint released on Thursday.

“Be careful of those things, man, the recorders and all those things,” he was recorded saying. “A lot of guys,” he continued, were “working to put a lot of people away, man, believe that.”
