Cops raided the Flatiron District offices of an interior-construction company yesterday, leaving with boxes of business records, according to a law-enforcement source.

Manhattan prosecutors declined to comment on the probe of Lehr Construction. Company exec Gerald Lazar could not immediately be reached for comment.

It would not be Lazar’s first brush with law enforcement — he pleaded guilty to bribery 12 years ago as part of a larger bid-rigging scheme involving his and other firms in the lucrative interior-construction industry.
